DevDocs is made of two pieces: a Ruby scraper that generates the documentation and metadata, and a JavaScript app powered by a small Sinatra app. Finally, point your browser at localhost:9292 (the first request will take a few seconds to compile the assets). You're all set.

I can't recommend devdocs.io enough! It's such a fantastic resource. * provides a consistent UI across all docs which is fantastic when you are switching between several while developing. * Is updated with terrifying frequency (I don't think I've ever opened it and NOT had some kind of docs update notification!)

A development document refers to a document that is created, reviewed, and implemented by development teams in the software industry. These documents include proposals, user requirements, test and review reports, and self-reflective documents that analyze the development process.
