+# api mode
+
+use sif's json output for automation and integration.
+
+## enabling api mode
+
+```bash
+./sif -u https://example.com -api
+```
+
+## output format
+
+api mode outputs json to stdout:
+
+```json
+{
+  "url": "https://example.com",
+  "results": [
+    {
+      "id": "module-id",
+      "data": {
+        "module_id": "module-id",
+        "target": "https://example.com",
+        "findings": [
+          {
+            "url": "https://example.com/.git/HEAD",
+            "severity": "high",
+            "evidence": "ref: refs/heads/main",
+            "extracted": {
+              "branch": "main"
+            }
+          }
+        ]
+      }
+    }
+  ]
+}
+```
+
+## fields
+
+### url
+
+the target url that was scanned.
+
+### results
+
+array of module results.
+
+### results[].id
+
+module identifier.
+
+### results[].data.findings
+
+array of security findings from the module.
+
+### findings[].url
+
+the specific url where the finding was detected.
+
+### findings[].severity
+
+severity level: `info`, `low`, `medium`, `high`, `critical`
+
+### findings[].evidence
+
+evidence that triggered the finding (matched content, etc).
+
+### findings[].extracted
+
+extracted data from the response (versions, keys, etc).
+
+## examples
+
+### save to file
+
+```bash
+./sif -u https://example.com -api -am > results.json
+```
+
+### pipe to jq
+
+```bash
+./sif -u https://example.com -api -am | jq '.results[].data.findings[]'
+```
+
+### filter high severity
+
+```bash
+./sif -u https://example.com -api -am | jq '.results[].data.findings[] | select(.severity == "high")'
+```
+
+### extract urls
+
+```bash
+./sif -u https://example.com -api -am | jq -r '.results[].data.findings[].url'
+```
+
+## ci/cd integration
+
+### github actions
+
+```yaml
+- name: run sif scan
+  run: |
+    ./sif -u ${{ env.TARGET_URL }} -api -am > sif-results.json
+
+- name: check for high severity findings
+  run: |
+    HIGH_COUNT=$(jq '[.results[].data.findings[] | select(.severity == "high" or .severity == "critical")] | length' sif-results.json)
+    if [ "$HIGH_COUNT" -gt 0 ]; then
+      echo "Found $HIGH_COUNT high/critical severity findings"
+      exit 1
+    fi
+```
+
+### gitlab ci
+
+```yaml
+security_scan:
+  script:
+    - ./sif -u $TARGET_URL -api -am > sif-results.json
+    - |
+      if jq -e '.results[].data.findings[] | select(.severity == "critical")' sif-results.json > /dev/null; then
+        echo "Critical findings detected"
+        exit 1
+      fi
+  artifacts:
+    paths:
+      - sif-results.json
+```
+
+## multiple targets
+
+when scanning multiple urls, each target outputs a separate json object:
+
+```bash
+./sif -u https://site1.com,https://site2.com -api
+```
+
+outputs:
+
+```json
+{"url":"https://site1.com","results":[...]}
+{"url":"https://site2.com","results":[...]}
+```
+
+use `jq -s` to combine into an array:
+
+```bash
+./sif -u https://site1.com,https://site2.com -api | jq -s '.'
+```
+
+## notes
+
+- api mode suppresses banner and interactive output
+- all output goes to stdout
+- errors and warnings still go to stderr
+- combine with `-l` flag to also save detailed logs

+# configuration
+
+runtime configuration options for sif.
+
+## environment variables
+
+### SHODAN_API_KEY
+
+required for shodan lookups.
+
+```bash
+export SHODAN_API_KEY=your-api-key-here
+./sif -u https://example.com -shodan
+```
+
+## command line options
+
+### timeout
+
+default request timeout is 10 seconds.
+
+```bash
+# increase for slow targets
+./sif -u https://example.com -t 30s
+
+# decrease for fast scans
+./sif -u https://example.com -t 5s
+```
+
+### threads
+
+default is 10 concurrent threads.
+
+```bash
+# more threads for faster scanning
+./sif -u https://example.com --threads 50
+
+# fewer threads to reduce load
+./sif -u https://example.com --threads 5
+```
+
+### logging
+
+save output to files:
+
+```bash
+./sif -u https://example.com -l ./logs
+```
+
+creates timestamped log files in the specified directory.
+
+### debug mode
+
+enable verbose logging:
+
+```bash
+./sif -u https://example.com -d
+```
+
+## user modules
+
+place custom modules in:
+
+- linux/macos: `~/.config/sif/modules/`
+- windows: `%LOCALAPPDATA%\sif\modules\`
+
+### directory structure
+
+```
+~/.config/sif/
+├── modules/
+│   ├── http/
+│   │   └── my-sqli-check.yaml
+│   ├── recon/
+│   │   └── custom-paths.yaml
+│   └── my-module.yaml
+```
+
+modules can be organized in subdirectories or placed directly in the modules folder.
+
+### overriding built-in modules
+
+user modules with the same id as built-in modules will override them:
+
+```yaml
+# ~/.config/sif/modules/sqli-error-based.yaml
+# this overrides the built-in sqli-error-based module
+
+id: sqli-error-based
+info:
+  name: my custom sqli check
+  # ...
+```
+
+## performance tuning
+
+### fast scans
+
+```bash
+./sif -u https://example.com \
+  --threads 50 \
+  -t 5s \
+  -dirlist small \
+  -dnslist small
+```
+
+### thorough scans
+
+```bash
+./sif -u https://example.com \
+  --threads 10 \
+  -t 30s \
+  -dirlist large \
+  -dnslist large \
+  -ports full
+```
+
+### low-impact scans
+
+reduce load on target:
+
+```bash
+./sif -u https://example.com \
+  --threads 2 \
+  -t 10s
+```
+
+## output formats
+
+### console (default)
+
+human-readable output with colors and formatting.
+
+### json (api mode)
+
+```bash
+./sif -u https://example.com -api
+```
+
+returns structured json:
+
+```json
+{
+  "url": "https://example.com",
+  "results": [
+    {
+      "id": "sqli-error-based",
+      "data": {
+        "findings": [...]
+      }
+    }
+  ]
+}
+```
+
+### log files
+
+```bash
+./sif -u https://example.com -l ./logs
+```
+
+creates separate log files for each scan type.

+4. integrate in `sif.go`
+
+see existing scans for examples.

+
+create a yaml file in `modules/`:
+
+```yaml
+id: my-new-module

+        - 200
+```
+
+see [modules.md](modules.md) for the full format.
+
+## module system internals
+
+the module system is in `internal/modules/`:
+
+- `module.go` - core interface and types
+- `registry.go` - module registration
+- `loader.go` - discovery and loading
+- `yaml.go` - yaml parsing
+- `executor.go` - http execution
+
+### adding a new module type
+
+1. add type constant to `module.go`
+2. implement executor in new file
+3. update loader to handle new extension/type
+
+## testing
+
+### unit tests
+
+```bash
+go test ./internal/...
+```
+
+### functional test
+
+```bash
+./sif -u https://example.com -am
+```
+
+### test modules
+
+```bash
+./sif -lm  # list modules
+./sif -u https://example.com -m my-module -d  # test specific module
+```
+
+## pull requests
+
+1. fork the repository
+2. create a feature branch
+3. make changes
+4. run `gofmt -w .` and `golangci-lint run`
+5. submit pr
+
+### commit messages

+# quickstart
+
+get up and running with sif in minutes.
+
+## basic scan
+
+run a basic scan against a target:
+
+```bash
+./sif -u https://example.com
+```
+
+this performs a base scan checking robots.txt, common files, and basic reconnaissance.
+
+## add more scans
+
+enable additional scan types with flags:
+
+```bash
+# directory fuzzing
+./sif -u https://example.com -dirlist medium
+
+# subdomain enumeration
+./sif -u https://example.com -dnslist small
+
+# port scanning
+./sif -u https://example.com -ports common
+
+# framework detection
+./sif -u https://example.com -framework
+```
+
+## run modules
+
+sif has a modular architecture with yaml-based security checks:
+
+```bash
+# list available modules
+./sif -lm
+
+# run all modules
+./sif -u https://example.com -am
+
+# run specific modules
+./sif -u https://example.com -m sqli-error-based,xss-reflected
+
+# run by tag
+./sif -u https://example.com -mt owasp-top10
+```
+
+## multiple targets
+
+scan multiple urls:
+
+```bash
+./sif -u https://site1.com,https://site2.com
+```
+
+or from a file:
+
+```bash
+./sif -f targets.txt
+```
+
+## save output
+
+save results to a log directory:
+
+```bash
+./sif -u https://example.com -l ./logs
+```
+
+## json output
+
+for automation, use api mode:
+
+```bash
+./sif -u https://example.com -api

+# scans
+
+detailed information about sif's built-in security scans.
+
+## base scan
+
+runs automatically unless `-noscan` is specified.
+
+checks:
+- robots.txt parsing
+- common files (sitemap.xml, security.txt, etc)
+- basic reconnaissance
+
+## directory fuzzing (-dirlist)
+
+brute-forces directories and files using wordlists.
+
+### sizes
+
+| size | entries | use case |
+|------|---------|----------|
+| small | ~1k | quick scan, low noise |
+| medium | ~10k | balanced coverage |
+| large | ~100k | thorough, takes longer |
+
+### what it finds
+
+- hidden directories (/admin, /backup, /config)
+- backup files (.bak, .old, .zip)
+- configuration files
+- development artifacts
+
+## subdomain enumeration (-dnslist)
+
+discovers subdomains via dns brute-forcing.
+
+### sizes
+
+| size | entries | use case |
+|------|---------|----------|

+| large | ~100k | comprehensive |
+
+### what it finds
+
+- dev/staging environments
