Read the Docs hosts documentation, making it fully searchable and easy to find. You can import your docs using any major version control system, including Mercurial, Git, Subversion, and Bazaar. It also supports webhooks so your docs get built when you commit code. There's also support for versioning so you can build docs from tagged versions of your code in your repository. You can even create docs on the site. It's free and simple.

This site launched in December 2010 with an initial batch of content. Minor pieces have been added and changed since then.

JavaScript Garden is a growing collection of documentation about the most quirky parts of the JavaScript programming language. It gives advice to avoid common mistakes, subtle bugs, as well as performance issues and bad practices that non-expert JavaScript programmers may encounter on their endeavours into the depths of the language.
