+[Cargo](http://doc.crates.io/index.html) is the Rust package manager providing access to libraries
 beyond the standard one, and its website contains lots of good documentation.
 
 [`rustdoc`](book/documentation.html) is the Rust's documentation generator, a tool converting
 annotated source code into HTML docs.
 
-A bunch of non-official tools are available, such as [Racer](https://github.com/phildawes/racer)

-# Community & Getting Help
-
-If you need help with something, or just want to talk about Rust with others,
-there are a few places you can do that:
-
-The Rust IRC channels on [irc.mozilla.org](irc://irc.mozilla.org/) are the
-fastest way to get help.
-[`#rust`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust) is
-the general discussion channel, and you'll find people willing to help you with
-any questions you may have.
-
-There are also three specialty channels:
-[`#rust-gamedev`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-gamedev)
-and
-[`#rust-osdev`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-osdev)
-are for game development and operating system development, respectively.
-There's also
-[`#rust-internals`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-internals), which is for discussion of the development of Rust itself.
-
-You can also get help on [Stack
-Overflow](https://stackoverflow.com/questions/tagged/rust). Searching for your
-problem might reveal someone who has asked it before!
-
-There is an active [subreddit](https://reddit.com/r/rust) with lots of
-discussion and news about Rust.
-
-There is also a [user forum](https://users.rust-lang.org), for all
-user-oriented discussion, and a [developer
-forum](https://internals.rust-lang.org/), where the development of Rust
-itself is discussed.
