+- Remember that users might search for your issue in the future, so please give it a meaningful title to help others.
 - The issue should clearly explain the reason for opening, the proposal if you have any, and any relevant technical information.
 
 ## Pull Requests
 
 1. Every Pull Request should have an associated bug or feature issue unless you are fixing a trivial documentation issue.
-1. Your PR is more likely to be accepted if it focuses on just one change.
-1. Describe what the PR does. There's no convention enforced, but please try to be concise and descriptive. Treat the PR description as a commit message. Titles that starts with "fix"/"add"/"improve"/"remove" are good examples.
-1. Please add the associated Issue in the PR description.
-1. There's no need to add or tag reviewers.
-1. If a reviewer commented on your code or asked for changes, please remember to mark the discussion as resolved after you address it. PRs with unresolved issues should not be merged (even if the comment is unclear or requires no action from your side).
-1. Please include a comment with the results before and after your change.
-1. Your PR is more likely to be accepted if it includes tests (We have not historically been very strict about tests, but we would like to improve this!).
-1. If your PR affects the user experience in some way, please update the Readme and the CLI help accordingly.
+4. Please add the associated Issue link in the PR description.
+2. Your PR is more likely to be accepted if it focuses on just one change.
+5. There's no need to add or tag reviewers.
+6. If a reviewer commented on your code or asked for changes, please remember to respond with comment. Do not mark discussion as resolved. It's up to reviewer to mark it resolved (in case if suggested fix addresses problem properly). PRs with unresolved issues should not be merged (even if the comment is unclear or requires no action from your side).
+7. Please include a comment with the results before and after your change.
+8. Your PR is more likely to be accepted if it includes tests (We have not historically been very strict about tests, but we would like to improve this!).
+9. If your PR affects the user experience in some way, please update the README.md and the CLI help accordingly.
+
+### Title
+It is not that strict, but we use the title conventions in this repository.
+Each commit message doesn't have to follow the conventions as long as it is clear and descriptive since it will be squashed and merged.
+
+#### Format of the title
+
+```
+<type>(<scope>): <subject>
+```
+
+The `type` and `scope` should always be lowercase as shown below.
+
+**Allowed `<type>` values:**
+  - **feat** for a new feature for the user, not a new feature for build script. Such commit will trigger a release bumping a MINOR version.
+  - **fix** for a bug fix for the user, not a fix to a build script. Such commit will trigger a release bumping a PATCH version.
+  - **perf** for performance improvements. Such commit will trigger a release bumping a PATCH version.
+  - **docs** for changes to the documentation.
+  - **style** for formatting changes, missing semicolons, etc.
+  - **refactor** for refactoring production code, e.g. renaming a variable.
+  - **test** for adding missing tests, refactoring tests; no production code change.
+  - **build** for updating build configuration, development tools or other changes irrelevant to the user.
+  - **chore** for updates that do not apply to the above, such as dependency updates.
+
+**Example `<scope>` values:**
+- alpine
+- redhat
+- ruby
+- python
+- terraform
+- report
+- etc.
+ 
+The `<scope>` can be empty (e.g. if the change is a global or difficult to assign to a single component), in which case the parentheses are omitted.
+
+#### Example titles
+
+```
+feat(alma): add support for AlmaLinux
+```
+
+```
+fix(oracle): handle advisories with ksplice versions
+```
+
+```
+docs(misconf): add comparison with Conftest and TFsec
+```
+
+```
+chore(deps): bump go.uber.org/zap from 1.19.1 to 1.20.0
+```
+
+**NOTE**: please do not use `chore(deps): update fanal` and something like that if you add new features or fix bugs in Trivy-related projects.
+The PR title should describe what the PR adds or fixes even though it just updates the dependency in Trivy.
+
+### Unit tests
+Your PR must pass all the unit tests. You can test it as below.
+
+```
+$ make test
+```
+
+### Integration tests
+Your PR must pass all the integration tests. You can test it as below.
+
+```
+$ make test-integration
+```
+
+### Documentation
+You can build the documents as below and view it at http://localhost:8000.
+
+```
+$ make mkdocs-serve
+```
 
 ## Understand where your pull request belongs
 
 Trivy is composed of several different repositories that work together:
 
 - [Trivy](https://github.com/aquasecurity/trivy) is the client-side, user-facing, command line tool.
-- [vuln-list](https://github.com/aquasecurity/vuln-list) is a vulnerabilities database, aggregated from different sources, and normalized for easy consumption. This of this as the "server" side of the trivy command line tool. **There should be no pull requests to this repo**

+# Air-Gapped Environment
+
+Trivy can be used in air-gapped environments. Note that an allowlist is [here][allowlist].
+
+## Air-Gapped Environment for vulnerabilities
+
+### Download the vulnerability database
+At first, you need to download the vulnerability database for use in air-gapped environments.
+Please follow [oras installation instruction][oras].
+
+Download `db.tar.gz`:
+
+```
+$ oras pull ghcr.io/aquasecurity/trivy-db:2 -a
+```
+
+### Transfer the DB file into the air-gapped environment
+The way of transfer depends on the environment.
+
+```
+$ rsync -av -e ssh /path/to/db.tar.gz [user]@[host]:dst
+```
+
+### Put the DB file in Trivy's cache directory
+You have to know where to put the DB file. The following command shows the default cache directory.
+
+```
+$ ssh user@host
+$ trivy -h | grep cache
+   --cache-dir value  cache directory (default: "/home/myuser/.cache/trivy") [$TRIVY_CACHE_DIR]
+```
+
+Put the DB file in the cache directory + `/db`.
+
+```
+$ mkdir -p /home/myuser/.cache/trivy/db
+$ cd /home/myuser/.cache/trivy/db
+$ tar xvf /path/to/db.tar.gz -C /home/myuser/.cache/trivy/db
+x trivy.db
+x metadata.json
+$ rm /path/to/db.tar.gz
+```
+
+In an air-gapped environment it is your responsibility to update the Trivy database on a regular basis, so that the scanner can detect recently-identified vulnerabilities. 
+
+### Run Trivy with --skip-update and --offline-scan option
+In an air-gapped environment, specify `--skip-update` so that Trivy doesn't attempt to download the latest database file.
+In addition, if you want to scan Java dependencies such as JAR and pom.xml, you need to specify `--offline-scan` since Trivy tries to issue API requests for scanning Java applications by default.
+
+```
+$ trivy image --skip-update --offline-scan alpine:3.12
+```
+
+## Air-Gapped Environment for misconfigurations
+
+### Download misconfiguration policies
+At first, you need to download misconfiguration policies for use in air-gapped environments.
+Please follow [oras installation instruction][oras].
+
+Download `bundle.tar.gz`:
+
+```
+$ oras pull ghcr.io/aquasecurity/appshield:latest -a
+```
+
+### Transfer misconfiguration policies into the air-gapped environment
+The way of transfer depends on the environment.
+
+```
+$ rsync -av -e ssh /path/to/bundle.tar.gz [user]@[host]:dst
+```
+
+### Put the misconfiguration policies in Trivy's cache directory
+You have to know where to put the misconfiguration policies file. The following command shows the default cache directory.
+
+```
+$ ssh user@host
+$ trivy -h | grep cache
+   --cache-dir value  cache directory (default: "/home/myuser/.cache/trivy") [$TRIVY_CACHE_DIR]
+```
+
+Put the misconfiguration policies file in the cache directory + `/policy/content`.
+
+```
+$ mkdir -p /home/myuser/.cache/trivy/policy/content
+$ cd /home/myuser/.cache/trivy/policy/content
+$ mv /path/to/bundle.tar.gz .
+```
+
+Then, decompress it.
+`bundle.tar.gz ` file includes two folders: `docker`, `kubernetes` and file: `.manifest`.
+
+```
+$ tar xvf bundle.tar.gz 
+x ./docker/
+...
+x ./kubernetes/
+...
+x ./.manifest
+$ rm bundle.tar.gz
+```
+
+In an air-gapped environment it is your responsibility to update policies on a regular basis, so that the scanner can detect recently-identified misconfigurations. 
+
+### Run Trivy with --skip-policy-update option
+In an air-gapped environment, specify `--skip-policy-update` so that Trivy doesn't attempt to download the latest misconfiguration policies.
+
+```
+$ trivy conf --skip-policy-update /path/to/conf
+```

+# Embed in Dockerfile
+
+Scan your image as part of the build process by embedding Trivy in the
+Dockerfile. This approach can be used to update Dockerfiles currently using
+Aqua’s [Microscanner][microscanner].
+
+```bash
+$ cat Dockerfile
+FROM alpine:3.7
+
+RUN apk add curl \
+    && curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin \
+    && trivy rootfs --exit-code 1 --no-progress /
+
+$ docker build -t vulnerable-image .
+```
+Alternatively you can use Trivy in a multistage build. Thus avoiding the
+insecure `curl | sh`. Also the image is not changed.
+```bash
+[...]
+# Run vulnerability scan on build image
+FROM build AS vulnscan
+COPY --from=aquasec/trivy:latest /usr/local/bin/trivy /usr/local/bin/trivy

+# GitLab CI
+
+If you're a GitLab Ultimate customer, GitLab 14.0 and above include out-of-the-box integration with Trivy. To enable it for your project, simply add the container scanning template to your `.gitlab-ci.yml` file. For more details, please refer to [GitLab's documentation](https://docs.gitlab.com/ee/user/application_security/container_scanning/).
+
+If you're using an earlier version of GitLab, you can still use the new integration by copying the [contents of the 14.0 template](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/gitlab/ci/templates/Security/Container-Scanning.gitlab-ci.yml) to your configuration.
+
+Alternatively, you can always use the example configurations below.

+### GitLab CI using Trivy container
+
+To scan a previously built image that has already been pushed into the
+GitLab container registry the following CI job manifest can be used.
+Note that `entrypoint` needs to be unset for the `script` section to work.
+In case of a non-public GitLab project Trivy additionally needs to
+authenticate to the registry to be able to pull your application image.
+Finally, it is not necessary to clone the project repo as we only work
+with the container image.
+
+```yaml
+container_scanning:
+  image:
+    name: docker.io/aquasec/trivy:latest
+    entrypoint: [""]
+  variables:
+    # No need to clone the repo, we exclusively work on artifacts.  See

+
+### Gitlab CI alternative template
+
+Depending on the edition of gitlab you have or your desired workflow, the
+container scanning template may not meet your needs. As an addition to the
+above container scanning template, a template for
+[code climate](https://docs.gitlab.com/ee/user/project/merge_requests/code_quality.html)
+has been included. The key things to update from the above examples are
+the `template` and `report` type. An updated example is below.
+
+```yaml
+stages:
+  - test
+
+trivy:
+  stage: test

+  # Enables https://docs.gitlab.com/ee/user/application_security/container_scanning/ (Container Scanning report is available on GitLab EE Ultimate or GitLab.com Gold)
+  artifacts:
+    paths:
+      - gl-codeclimate.json
+    reports:
+      codequality: gl-codeclimate.json
+```
+
+Currently gitlab only supports a single code quality report. There is an
+open [feature request](https://gitlab.com/gitlab-org/gitlab/-/issues/9014)
+to support multiple reports. Until this has been implemented, if you
+already have a code quality report in your pipeline, you can use
+`jq` to combine reports. Depending on how you name your artifacts, it may
+be necessary to rename the artifact if you want to reuse the name. To then
+combine the previous artifact with the output of trivy, the following `jq`
+command can be used, `jq -s 'add' prev-codeclimate.json trivy-codeclimate.json > gl-codeclimate.json`.

+# Plugins
+Trivy provides a plugin feature to allow others to extend the Trivy CLI without the need to change the Trivycode base.
+This plugin system was inspired by the plugin system used in [kubectl][kubectl], [Helm][helm], and [Conftest][conftest].
+
+## Overview
+Trivy plugins are add-on tools that integrate seamlessly with Trivy.
+They provide a way to extend the core feature set of Trivy, but without requiring every new feature to be written in Go and added to the core tool.
+
+- They can be added and removed from a Trivy installation without impacting the core Trivy tool.
+- They can be written in any programming language.
+- They integrate with Trivy, and will show up in Trivy help and subcommands.
+
+!!! warning
+    Trivy plugins available in public are not audited for security.
+    You should install and run third-party plugins at your own risk, since they are arbitrary programs running on your machine.
+
+
+## Installing a Plugin
+A plugin can be installed using the `trivy plugin install` command.
+This command takes a url and will download the plugin and install it in the plugin cache.
+
+Trivy adheres to the XDG specification, so the location depends on whether XDG_DATA_HOME is set.
+Trivy will now search XDG_DATA_HOME for the location of the Trivy plugins cache.
+The preference order is as follows:
+
+- XDG_DATA_HOME if set and .trivy/plugins exists within the XDG_DATA_HOME dir
+- ~/.trivy/plugins
+
+Under the hood Trivy leverages [go-getter][go-getter] to download plugins.
+This means the following protocols are supported for downloading plugins:
+
+- OCI Registries
+- Local Files
+- Git
+- HTTP/HTTPS
+- Mercurial
+- Amazon S3
+- Google Cloud Storage
+
+For example, to download the Kubernetes Trivy plugin you can execute the following command:
+
+```bash
+$ trivy plugin install github.com/aquasecurity/trivy-plugin-kubectl
+```
+## Using Plugins
+Once the plugin is installed, Trivy will load all available plugins in the cache on the start of the next Trivy execution.
+A plugin will be made in the Trivy CLI based on the plugin name.
+To display all plugins, you can list them by `trivy --help`
+
+```bash
+$ trivy --help
+NAME:
+   trivy - A simple and comprehensive vulnerability scanner for containers
+
+USAGE:
+   trivy [global options] command [command options] target
+
+VERSION:
+   dev
+
+COMMANDS:
+   image, i          scan an image
+   filesystem, fs    scan local filesystem
+   repository, repo  scan remote repository
+   client, c         client mode
+   server, s         server mode
+   plugin, p         manage plugins
+   kubectl           scan kubectl resources
+   help, h           Shows a list of commands or help for one command
+```
+
+As shown above, `kubectl` subcommand exists in the `COMMANDS` section.
+To call the kubectl plugin and scan existing Kubernetes deployments, you can execute the following command:
+
+```
+$ trivy kubectl deployment <deployment-id> -- --ignore-unfixed --severity CRITICAL
+```
+
+Internally the kubectl plugin calls the kubectl binary to fetch information about that deployment and passes the using images to Trivy.
+You can see the detail [here][trivy-plugin-kubectl].
+
+If you want to omit even the subcommand, you can use `TRIVY_RUN_AS_PLUGIN` environment variable.
+
+```bash
+$ TRIVY_RUN_AS_PLUGIN=kubectl trivy job your-job -- --format json
+```
+
+## Installing and Running Plugins on the fly
+`trivy plugin run` installs a plugin and runs it on the fly.
+If the plugin is already present in the cache, the installation is skipped.
+
+```bash
+trivy plugin run github.com/aquasecurity/trivy-plugin-kubectl pod your-pod -- --exit-code 1
+```
+
+## Uninstalling Plugins
+Specify a plugin name with `trivy plugin uninstall` command.
+
+```bash
+$ trivy plugin uninstall kubectl
+```
+
+## Building Plugins
+Each plugin has a top-level directory, and then a plugin.yaml file.
+
+```bash
+your-plugin/
+  |
+  |- plugin.yaml
+  |- your-plugin.sh
+```
+
+In the example above, the plugin is contained inside of a directory named `your-plugin`.
+It has two files: plugin.yaml (required) and an executable script, your-plugin.sh (optional).
+
+The core of a plugin is a simple YAML file named plugin.yaml.
+Here is an example YAML of trivy-plugin-kubectl plugin that adds support for Kubernetes scanning.
+
+```yaml
+name: "kubectl"
+repository: github.com/aquasecurity/trivy-plugin-kubectl
+version: "0.1.0"
+usage: scan kubectl resources
+description: |-
+  A Trivy plugin that scans the images of a kubernetes resource.
+  Usage: trivy kubectl TYPE[.VERSION][.GROUP] NAME
+platforms:
+  - selector: # optional
+      os: darwin
+      arch: amd64
+    uri: ./trivy-kubectl # where the execution file is (local file, http, git, etc.)
+    bin: ./trivy-kubectl # path to the execution file
+  - selector: # optional
+      os: linux
+      arch: amd64
+    uri: https://github.com/aquasecurity/trivy-plugin-kubectl/releases/download/v0.1.0/trivy-kubectl.tar.gz
+    bin: ./trivy-kubectl
+```
+
+The `plugin.yaml` field should contain the following information:
+
+- name: The name of the plugin. This also determines how the plugin will be made available in the Trivy CLI. For example, if the plugin is named kubectl, you can call the plugin with `trivy kubectl`. (required)
+- version: The version of the plugin. (required)
+- usage: A short usage description. (required)
+- description: A long description of the plugin. This is where you could provide a helpful documentation of your plugin. (required)
+- platforms: (required)
+  - selector: The OS/Architecture specific variations of a execution file. (optional)
+    - os: OS information based on GOOS (linux, darwin, etc.) (optional)
+    - arch: The architecture information based on GOARCH (amd64, arm64, etc.) (optional)
+  - uri: Where the executable file is. Relative path from the root directory of the plugin or remote URL such as HTTP and S3. (required)
+  - bin: Which file to call when the plugin is executed. Relative path from the root directory of the plugin. (required)
+
+The following rules will apply in deciding which platform to select:
+
+- If both `os` and `arch` under `selector` match the current platform, search will stop and the platform will be used.
+- If `selector` is not present, the platform will be used.
+- If `os` matches and there is no more specific `arch` match, the platform will be used.
+- If no `platform` match is found, Trivy will exit with an error.
+
+After determining platform, Trivy will download the execution file from `uri` and store it in the plugin cache.
+When the plugin is called via Trivy CLI, `bin` command will be executed.
+
+The plugin is responsible for handling flags and arguments. Any arguments are passed to the plugin from the `trivy` command.

-# Air-gapped environment
-Trivy can be used in air-gapped environments.
-
-## Download the vulnerability database
-At first, you need to download the vulnerability database for use in air-gapped environments.
-Go to [trivy-db](https://github.com/aquasecurity/trivy-db/releases) and download `trivy-offline.db.tgz` in the latest release.
-If you download `trivy-light-offline.db.tgz`, you have to run Trivy with `--light` option.
-
-```
-$ wget https://github.com/aquasecurity/trivy-db/releases/latest/download/trivy-offline.db.tgz
-```
-
-
-## Transfer the DB file into the air-gapped environment
-The way of transfer depends on the environment.
-
-```
-$ rsync -av -e ssh /path/to/trivy-offline.db.tgz [user]@[host]:dst
-```
-
-## Put the DB file in Trivy's cache directory
-You have to know where to put the DB file. The following command shows the default cache directory.
-
-```
-$ ssh user@host
-$ trivy -h | grep cache
-   --cache-dir value  cache directory (default: "/home/myuser/.cache/trivy") [$TRIVY_CACHE_DIR]
-```
-
-Put the DB file in the cache directory + `/db`.
-
-```
-$ mkdir -p /home/myuser/.cache/trivy/db
-$ cd /home/myuser/.cache/trivy/db
-$ mv /path/to/trivy-offline.db.tgz .
-```
-
-Then, decompress it.
-`trivy-offline.db.tgz` file includes two files, `trivy.db` and `metadata.json`.
-
-```
-$ tar xvf trivy-offline.db.tgz
-x trivy.db
-x metadata.json
-$ rm trivy-offline.db.tgz
-```
-
-In an air-gapped environment it is your responsibility to update the Trivy database on a regular basis, so that the scanner can detect recently-identified vulnerabilities. 
-
-## Run Trivy with --skip-update option
-In an air-gapped environment, specify `--skip-update` so that Trivy doesn't attempt to download the latest database file.
-
-```
-$ trivy image --skip-update alpine:3.12

+# Overview
+
+Trivy detects two types of security issues:
+
+- [Vulnerabilities][vuln]
+- [Misconfigurations][misconf]
+
+Trivy can scan three different artifacts:
+
+- [Container Images][container]
+- [Filesystem][filesystem] and [Rootfs][rootfs]
+- [Git Repositories][repo]
+
+Trivy can be run in two different modes:
+
+- [Standalone][standalone]
+- [Client/Server][client-server]
+
+It is designed to be used in CI. Before pushing to a container registry or deploying your application, you can scan your local container image and other artifacts easily.
+See [Integrations][integrations] for details.
+
+## Features
+
+- Comprehensive vulnerability detection
+    - [OS packages][os] (Alpine, Red Hat Universal Base Image, Red Hat Enterprise Linux, CentOS, AlmaLinux, Rocky Linux, CBL-Mariner, Oracle Linux, Debian, Ubuntu, Amazon Linux, openSUSE Leap, SUSE Enterprise Linux, Photon OS and Distroless)
+    - [**Language-specific packages**][lang] (Bundler, Composer, Pipenv, Poetry, npm, yarn, Cargo, NuGet, Maven, and Go)
+- Detect IaC misconfigurations
+    - A wide variety of [built-in policies][builtin] are provided **out of the box**:
+        - Kubernetes
+        - Docker
+        - Terraform
+        - more coming soon
+    - Support custom policies
+- Simple
+    - Specify only an image name, a directory containing IaC configs, or an artifact name
+    - See [Quick Start][quickstart]
+- Fast
+    - The first scan will finish within 10 seconds (depending on your network). Consequent scans will finish in single seconds.
+    - Unlike other scanners that take long to fetch vulnerability information (~10 minutes) on the first run, and encourage you to maintain a durable vulnerability database, Trivy is stateless and requires no maintenance or preparation.
+- Easy installation
+    - `apt-get install`, `yum install` and `brew install` is possible (See [Installation](installation.md))
+    - **No pre-requisites** such as installation of DB, libraries, etc.
+- High accuracy
+    - **Especially Alpine Linux and RHEL/CentOS**
+    - Other OSes are also high
+- DevSecOps
+    - **Suitable for CI** such as Travis CI, CircleCI, Jenkins, GitLab CI, etc.
+    - See [CI Example][integrations]
+- Support multiple formats
+    - container image
+        - A local image in Docker Engine which is running as a daemon
+        - A local image in [Podman][podman] (>=2.0) which is exposing a socket
+        - A remote image in Docker Registry such as Docker Hub, ECR, GCR and ACR
+        - A tar archive stored in the `docker save` / `podman save` formatted file
+        - An image directory compliant with [OCI Image Format][oci]
+    - local filesystem and rootfs
+    - remote git repository
+
+Please see [LICENSE][license] for Trivy licensing information.

+# Troubleshooting
+
+## Scan
+### Timeout
+
+!!! error
+    ``` bash
+    $ trivy image ...
+    ...
+    analyze error: timeout: context deadline exceeded
+    ```
+
+Your scan may time out. Java takes a particularly long time to scan. Try increasing the value of the ---timeout option such as `--timeout 15m`.
+
+### Certification
+
+!!! error
+    Error: x509: certificate signed by unknown authority
+
+`TRIVY_INSECURE` can be used to allow insecure connections to a container registry when using SSL.
+
+```
+$ TRIVY_INSECURE=true trivy image [YOUR_IMAGE]
+```
+
+### GitHub Rate limiting
+
+!!! error
+    ``` bash
+    $ trivy image ...
+    ...
+    API rate limit exceeded for xxx.xxx.xxx.xxx.
+    ```
+
+Specify GITHUB_TOKEN for authentication
+https://developer.github.com/v3/#rate-limiting
+
+```
+$ GITHUB_TOKEN=XXXXXXXXXX trivy alpine:3.10
+```
+
+### Maven rate limiting
+
+!!! error
+    ``` bash
+    $ trivy image ...
+    ...
+    status 403 Forbidden from http://search.maven.org/solrsearch/select
+    ```
+
+Trivy calls Maven API for better detection of JAR files, but many requests may exceed rate limiting.
+If it happens frequently, try the `--offline-scan` option to stop Trivy from making API requests.
+This option affects only vulnerability scanning. The vulnerability database and builtin policies are downloaded as usual.
+If you want to skip them as well, you can try `--skip-update` and `--skip-policy-update`.
+
+Note that a number of vulnerabilities might be fewer than without the `--offline-scan` option.
+
+### Running in parallel takes same time as series run
+When running trivy on multiple images simultaneously, it will take same time as running trivy in series.  
+This is because of a limitation of boltdb.
+> Bolt obtains a file lock on the data file so multiple processes cannot open the same database at the same time. Opening an already open Bolt database will cause it to hang until the other process closes it.
+
+Reference : [boltdb: Opening a database][boltdb].
+
+[boltdb]: https://github.com/boltdb/bolt#opening-a-database
+
+### Error downloading vulnerability DB
+
+!!! error
+    FATAL failed to download vulnerability DB
+
+If trivy is running behind corporate firewall, you have to add the following urls to your allowlist.
+
+- ghcr.io
+- pkg-containers.githubusercontent.com
+
+### Old DB schema
+
+!!! error
+    --skip-update cannot be specified with the old DB schema.
+
+Trivy v0.23.0 or later requires Trivy DB v2. Please update your local database or follow [the instruction of air-gapped environment][air-gapped].
+
+## Homebrew
+### Scope error
+!!! error
+    Error: Your macOS keychain GitHub credentials do not have sufficient scope!
+
+```
+$ brew tap aquasecurity/trivy
+Error: Your macOS keychain GitHub credentials do not have sufficient scope!
+Scopes they need: none
+Scopes they have:
+Create a personal access token:
+https://github.com/settings/tokens/new?scopes=gist,public_repo&description=Homebrew
+echo 'export HOMEBREW_GITHUB_API_TOKEN=your_token_here' >> ~/.zshrc
+```
+
+Try:
+
+```
+$ printf "protocol=https\nhost=github.com\n" | git credential-osxkeychain erase
+```
+
+### Already installed
+!!! error
+    Error: aquasecurity/trivy/trivy 64 already installed
+
+```
+$ brew upgrade
+...
+Error: aquasecurity/trivy/trivy 64 already installed
+```
+
+Try:
+
+```
+$ brew unlink trivy && brew uninstall trivy
+($ rm -rf /usr/local/Cellar/trivy/64)
+$ brew install aquasecurity/trivy/trivy
+```
+
+
+## Others
+### Unknown error
+
+Try again with `--reset` option:
+
+```
+$ trivy image --reset

+`Trivy` (`tri` pronounced like **tri**gger, `vy` pronounced like en**vy**) is a simple and comprehensive [vulnerability][vulnerability]/[misconfiguration][misconf] scanner for containers and other artifacts.
+A software vulnerability is a glitch, flaw, or weakness present in the software or in an Operating System.
+`Trivy` detects vulnerabilities of [OS packages][os] (Alpine, RHEL, CentOS, etc.) and [language-specific packages][lang] (Bundler, Composer, npm, yarn, etc.).
+In addition, `Trivy` scans [Infrastructure as Code (IaC) files][iac] such as Terraform and Kubernetes, to detect potential configuration issues that expose your deployments to the risk of attack.
+`Trivy` is easy to use. Just install the binary and you're ready to scan.
+All you need to do for scanning is to specify a target such as an image name of the container.

+# Combined input
+
+## Overview
+Trivy usually scans each configuration file individually. 
+Sometimes it might be useful to compare values from different configuration files simultaneously.
+
+When `combine` is set to true, all config files under the specified directory are combined into one input data structure.
+
+!!! example
+    ```
+    __rego_input__ := {
+        "combine": false,
+    }
+    ```
+
+In "combine" mode, the `input` document becomes an array, where each element is an object with two fields:
+
+- `"path": "path/to/file"`: the relative file path of the respective file
+- `"contents": ...`: the parsed content of the respective file
+
+Now you can ensure that duplicate values match across the entirety of your configuration files.
+
+## Return value
+In "combine" mode, the `deny` entrypoint must return an object with two keys
+
+`filepath` (required)
+: the relative file path of the file being evaluated
+
+`msg` (required)
+: the message describing an issue
+
+!!! example
+    ```
+    deny[res] {
+        resource := input[i].contents
+        ... some logic ...
+
+    	res := {
+    		"filepath": input[i].path,
+    		"msg": "something bad",
+    	}

+# Custom Data
+
+Custom policies may require additional data in order to determine an answer.
+
+For example, an allowed list of resources that can be created. 
+Instead of hardcoding this information inside of your policy, Trivy allows passing paths to data files with the `--data` flag.
+
+Given the following yaml file:
+
+```bash
+$ cd examples/misconf/custom-data
+$ cat data/ports.yaml                                                                                                                                                                      [~/src/github.com/aquasecurity/trivy/examples/misconf/custom-data]

+    - "20"
+    - "20/tcp"
+    - "20/udp"
+    - "23"
+    - "23/tcp"
+```
+
+This can be imported into your policy:
+
+```rego
+import data.services
+
+ports := services.ports
+```
+
+Then, you need to pass data paths through `--data` option.
+Trivy recursively searches the specified paths for JSON (`*.json`) and YAML (`*.yaml`) files.
+
+```bash
+$ trivy conf --policy ./policy --data data --namespaces user ./configs
+```

+# Examples
+
+## Custom Policy
+### Kubernetes
+See [here][k8s].
+
+The custom policy is defined in `user.kubernetes.ID001` package.
+You need to pass the package prefix you want to evaluate through `--namespaces` option.
+In this case, the package prefix should be `user`, `user.kuberntes`, or `user.kubernetes.ID001`.
+
+### Dockerfile
+See [here][dockerfile].
+
+The input will be a dictionary of stages.
+

+# Custom Policies
+
+## Overview
+You can write custom policies in [Rego][rego].
+Once you finish writing custom policies, you can pass the directory where those policies are stored with `--policy` option.
+
+``` bash
+trivy conf --policy /path/to/custom_policies --namespaces user /path/to/config_dir
+```
+
+As for `--namespaces` option, the detail is described as below.
+
+### File formats
+If a file name matches the following file patterns, Trivy will parse the file and pass it as input to your Rego policy.
+
+| File format    | File pattern                                     |
+| -------------- | ------------------------------------------------ |
+| JSON           | `*.json`                                         |
+| YAML           | `*.yaml`                                         |
+| TOML           | `*.toml`                                         |
+| HCL            | `*.hcl`, `*.hcl1`, and `*.hcl2`                  |
+| Dockerfile     | `Dockerfile`, `Dockerfile.*`, and `*.Dockerfile` |
+
+### Configuration languages
+In the above general file formats, Trivy automatically identifies the following types of configuration files:
+
+- Ansible (YAML)
+- CloudFormation (JSON/YAML)
+- Kubernetes (JSON/YAML)
+
+This is useful for filtering inputs, as described below.
+
+!!! warning
+    Custom policies do not support Terraform at the moment.
+
+## Rego format
+A single package must contain only one policy.
+
+!!!example
+    ``` rego
+    package user.kubernetes.ID001
+    
+    __rego_metadata__ := {
+    	"id": "ID001",
+    	"title": "Deployment not allowed",
+    	"severity": "LOW",
+    	"type": "Custom Kubernetes Check",
+    	"description": "Deployments are not allowed because of some reasons.",
+    }
+
+    __rego_input__ := {
+        "selector": [
+            {"type": "kubernetes"},
+        ],
+    }
+    
+    deny[msg] {
+    	input.kind == "Deployment"
+    	msg = sprintf("Found deployment '%s' but deployments are not allowed", [input.metadata.name])
+    }
+    ```
+
+In this example, ID001 "Deployment not allowed" is defined under `user.kubernetes.ID001`.
+If you add a new custom policy, it must be defined under a new package like `user.kubernetes.ID002`.
+
+### Policy structure
+
+`package` (required)
+:   - MUST follow the Rego's [specification][package]
+    - MUST be unique per policy
+    - SHOULD include policy id for uniqueness
+    - MAY include the group name such as `kubernetes` for clarity
+        - Group name has no effect on policy evaluation
+
+`__rego_metadata__` (optional)
+:   - SHOULD be defined for clarity since these values will be displayed in the scan results
+
+`__rego_input__` (optional)
+:   - MAY be defined when you want to specify input format
+
+`deny` (required)
+:   - SHOULD be `deny` or start with `deny_`
+        - Although `warn`, `warn_*`, `violation`, `violation_` also work for compatibility, `deny` is recommended as severity can be defined in `__rego_metadata__`.
+    - SHOULD return `string`
+        - Although `object` with `msg` field is accepted, other fields are dropped and `string` is recommended.
+        - e.g. `{"msg": "deny message", "details": "something"}`
+    
+
+### Package
+A package name must be unique per policy.
+
+!!!example
+    ``` rego
+    package user.kubernetes.ID001
+    ```
+
+By default, only `appshield.*` packages will be evaluated.
+If you define custom packages, you have to specify the package prefix via `--namespaces` option. 
+
+``` bash
+trivy conf --policy /path/to/custom_policies --namespaces user /path/to/config_dir
+```
+
+In this case, `user.*` will be evaluated.
+Any package prefixes such as `main` and `user` are allowed.
+
+### Metadata
+Metadata helps enrich Trivy's scan results with useful information.
+
+!!!example
+    ``` rego
+    __rego_metadata__ := {
+    	"id": "ID001",
+    	"title": "Deployment not allowed",
+    	"severity": "LOW",
+    	"type": "Custom Kubernetes Check",
+    	"description": "Deployments are not allowed because of some reasons.",
+    	"recommended_actions": "Remove Deployment",
+    	"url": "https://cloud.google.com/blog/products/containers-kubernetes/kubernetes-best-practices-resource-requests-and-limits",
+    }
+    ```
+  
+All fields under `__rego_metadata__` are optional.
+
+| Field name         | Allowed values                      | Default value | In table           | In JSON          |
+| ------------------ | ------------------------------------| :-----------: | :----------------: |:---------------: |
+| id                 | Any characters                      | N/A           | :material-check:   | :material-check: |
+| title              | Any characters                      | N/A           | :material-check:   | :material-check: |
+| severity           | `LOW`, `MEDIUM`, `HIGH`, `CRITICAL` | UNKNOWN       | :material-check:   | :material-check: |
+| type               | Any characters                      | N/A           | :material-check:   | :material-check: |
+| description        | Any characters                      |               | :material-close:   | :material-check: |
+| recommended_actions| Any characters                      |               | :material-close:   | :material-check: | 
+| url                | Any characters                      |               | :material-close:   | :material-check: |
+
+Some fields are displayed in scan results.
+
+``` bash
+deployment.yaml (kubernetes)

+Tests: 28 (SUCCESSES: 14, FAILURES: 14, EXCEPTIONS: 0)
+Failures: 14 (HIGH: 1)

++---------------------------+------------+-------------------------------------+----------+------------------------------------------+
+| Custom Kubernetes Check   |   ID001    | Deployment not allowed              |   LOW    | Found deployment 'test' but deployments  |
+|                           |            |                                     |          | are not allowed                          |
++---------------------------+------------+-------------------------------------+----------+------------------------------------------+
+```
+
+### Input
+You can specify input format via `__rego_input__`.
+All fields under `__rego_input` are optional.
+
+!!!example
+    ``` rego
+    __rego_input__ := {
+        "combine": false,
+        "selector": [
+            {"type": "kubernetes"},
+        ],
+    }
+    ```
+
+`combine` (boolean)
+: The details is [here](combine.md).
+
+`selector` (array)
+:   This option filters the input by file formats or configuration languages. 
+    In the above example, Trivy passes only Kubernetes files to this policy.
+    Even if Dockerfile exists in the specified directory, it will not be passed to the policy as input.
+
+    When configuration language such as Kubernetes is not identified, file format such as JSON will be used as `type`.
+    When configuration language is identified, it will overwrite `type`.
+    
+    !!! example
+        `pod.yaml` including Kubernetes Pod will be handled as `kubernetes`, not `yaml`.
+        `type` is overwritten by `kubernetes` from `yaml`.
+
+    `type` accepts `kubernetes`, `dockerfile`, `ansible`, `cloudformation`, `json`, `yaml`, `toml`, or `hcl`.

+# Testing
+It is highly recommended to write tests for your custom policies.
+
+## Rego testing
+To help you verify the correctness of your custom policies, OPA gives you a framework that you can use to write tests for your policies. 
+By writing tests for your custom policies you can speed up the development process of new rules and reduce the amount of time it takes to modify rules as requirements evolve.
+
+For more details, see [Policy Testing][opa-testing].
+
+!!! example
+    ```
+    package user.dockerfile.ID002
+
+    test_add_denied {
+        r := deny with input as {"stages": {"alpine:3.13": [
+            {"Cmd": "add", "Value": ["/target/resources.tar.gz", "resources.jar"]},
+            {"Cmd": "add", "Value": ["/target/app.jar", "app.jar"]},
+        ]}}
+
+        count(r) == 1
+        r[_] == "Consider using 'COPY /target/app.jar app.jar' command instead of 'ADD /target/app.jar app.jar'"
+    }
+    ```
+
+To write tests for custom policies, you can refer to existing tests under [AppShield][appshield].
+
+## Go testing
+[Fanal][fanal] which is a core library of Trivy can be imported as a Go library.
+You can scan config files in Go and test your custom policies using Go's testing methods, such as [table-driven tests][table].
+This allows you to use the actual configuration file as input, making it easy to prepare test data and ensure that your custom policies work in practice.
+
+In particular, Dockerfile and HCL need to be converted to structural data as input, which may be different from the expected input format.
+
+!!! tip
+    We recommend writing OPA and Go tests both since they have different roles, like unit tests and integration tests.
+
+The following example stores allowed and denied configuration files in a directory.
+`Successes` contains the result of successes, and `Failures` contains the result of failures.
+
+``` go
+{
+	name:  "disallowed ports",
+	input: "configs/",
+	fields: fields{
+		policyPaths: []string{"policy"},
+		dataPaths:   []string{"data"},
+		namespaces:  []string{"user"},
+	},
+	want: []types.Misconfiguration{
+		{
+			FileType: types.Dockerfile,
+			FilePath: "Dockerfile.allowed",
+			Successes: types.MisconfResults{
+				{
+					Namespace: "user.dockerfile.ID002",
+					PolicyMetadata: types.PolicyMetadata{
+						ID:          "ID002",
+						Type:        "Docker Custom Check",
+						Title:       "Disallowed ports exposed",
+						Severity:    "HIGH",
+					},
+				},
+			},
+		},
+		{
+			FileType: types.Dockerfile,
+			FilePath: "Dockerfile.denied",
+			Failures: types.MisconfResults{
+				{
+					Namespace: "user.dockerfile.ID002",
+					Message:   "Port 23 should not be exposed",
+					PolicyMetadata: types.PolicyMetadata{
+						ID:          "ID002",
+						Type:        "Docker Custom Check",
+						Title:       "Disallowed ports exposed",
+						Severity:    "HIGH",
+					},
+				},
+			},
+		},
+	},
+},
+```
+
+`Dockerfile.allowed` has one successful result in `Successes`, while `Dockerfile.denied` has one failure result in `Failures`.

+# Filesystem
+
+## Quick start
+
+Trivy scans a filesystem such as a virtual machine to detect misconfigurations.
+
+You have to specify `--security-checks config` to enable misconfiguration detection.
+
+```bash
+$ trivy fs --security-checks config /path/to/dir
+```
+
+Internally, it is the same as [config subcommand](iac.md).
+
+## Vulnerability and Misconfiguration scanning
+The difference between `fs` and `config` subcommand is that `fs` can detect both vulnerabilities and misconfiguration at the same time.
+
+You have to specify `--security-checks vuln,config` to enable vulnerability and misconfiguration detection.
