Welcome to the Rust Wiki. This is probably about 5 years too late - but it's here now.
We expect to use this as a place to document new features as we go along and try to explain older features. If you log in, you can help us do that - it would be very much appreciated.
To create a new page, just type the address in the address bar. It'll tell you that the page doesn't exist, and you can create it.
You can select the appropriate category for the page to have it show in the sidebar.
If you see an error on the site, you don't have to tweet us. You can just log in and press the edit page button to fix it yourself.
