 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.
-For example, to run capa with both a rule path and a signature path:
-```console
-$ capa -s /path/to/capa-sigs suspicious.exe
