This repository contains the YAML Schema used in the FTW tool. It is being maintained as code, so it will be easy to include as a library.
You will need the dstdocgen go generator for creating the documentation in markdown format. The tool is easily installed using:
go install github.com/projectdiscovery/yamldoc-go/cmd/docgen/dstdocgen@latest
Then you can run:
go run mage.go markdown
