+## Helpful Links and Information
+
+For people new to Rust, and just starting to contribute, or even for
+more seasoned developers, some useful places to look for information
+are:
+
+* The [Rust Internals forum][rif], a place to ask questions and
+  discuss Rust's internals
+* The [generated documentation for rust's compiler][gdfrustc]
+* The [rust referance][rr], even though it doesn't specifically talk about Rust's internals, its a great reasource nontheless
+* Although out of date, [Tom Lee's great blog article][tlgba] is very helpful
+* [rustaceans.org][ro] is helpful, but mostly dedicated to IRC
+* **Google**!
+* Don't be afraid to ask! The Rust community is friendly and helpful.
