Project structure

The commonmark package is just the parser as well as a simple HTML renderer which returns a string, mostly to facilitate checking CommonMark spec compliance. Most likely you want a specialised render for whatever framework you're using though.

Known renderer projects:

commonmark/commonmark is a CommonMark renderer, useful if you want to generate an AST and write out a document based on it.
commonmark/html is a HTML renderer included as part of this package.
