Xeme: I'd value your opinion on my new Ruby gem

In addition to project documentation, you've included a lot of code comments. You could adopt a standardized format and use it to generate API documentation. RDoc and YARD are two options. If I were reviewing this code at work, I would probably ask you to remove comments that explain what, not why.

That turns out to be a pretty common use case for markdown. Github, for example, renders your README.md is part of a git repo's "home" page. It's also common to have tooling that parses specially formatted comments in your source code and produce a documentation bundle, usually as a web page (ex. RDoc, YARD, JSDoc, etc.).
