<commit_before>Thank you for your interest in contributing to the Rust Reference!

There are a few ways of helping with the reference: critiquing the reference,
editing the reference, fixing incorrect information, adding examples and
glossary entries, and documenting new or otherwise undocumented features in
Rust.

For awhile, the Reference was basically ignored, and Rust continued gaining new
features or changing old ones. It was also basically the introduction document
before the first edition of the Rust book, and constantly in flux from the huge
churn of the language design before v1.0.0. So there's a lot that's wrong, too
teachy for people who should have basic understanding of Rust, or is too shallow
for the Reference. As such, we have the warning saying there's work that needs
to be done. Eventually, we plan to make sure everything is well documented
enough that we can remove the warning.

It is encouraged for you to read the [introduction] to familiarize yourself
with the kind of content the reference is expected to contain and the<commit_msg>Grammar fix<commit_after>Thank you for your interest in contributing to the Rust Reference!
