Docs

Here are the docs. The documents about Rust. Read the reference docs first, because those are likely to be correct, if incomplete. This wiki also has a number of useful articles of varying ages and accuracy.

The best source of up to date information is #rust on irc.mozilla.org. That is where most discussion about Rust takes place. A lot of decisions are made on rust-dev. New developments are often blogged in various places, which usually appear on r/rust.
