markdown

This generator creates a .md file for each requirement with useful information to consume the installed packages: libraries available, components, headers, and basic instructions to consume them using different build systems.

Although markdown files can be read in plain text, we highly recommend you to use any plugin to see it with proper rendering (browsers, IDEs,.. all of them have plugins that will render markdown documents).
