+Additionally, capa also supports analyzing [CAPE](https://github.com/kevoreilly/CAPEv2) sandbox reports for dynamic capabilty extraction.
+In order to use this, you first submit your sample to CAPE for analysis, and then run capa against the generated report (JSON).

 capa uses a collection of rules to identify capabilities within a program.
 These rules are easy to write, even for those new to reverse engineering.
 By authoring rules, you can extend the capabilities that capa recognizes.

 This directory contains FLIRT signatures that capa uses to identify library functions.
 Typically, capa will ignore library functions, which reduces false positives and improves runtime.

-This technique also doesn't set up the default library identification [signatures](https://github.com/mandiant/capa/tree/master/sigs). You can pass the signature directory using the `-s` argument.

 Importantly, you can configure pre-commit to run automatically before every commit by running:
 
-    ❯ pre-commit install --hook-type pre-commit
+    ❯ pre-commit install --hook-type=pre-commit
     pre-commit installed at .git/hooks/pre-commit

 This way you can ensure that you don't commit code style or formatting offenses.
