 # Crater
 
 [Crater](https://github.com/rust-lang/crater) is a tool for compiling and
-running tests for _every_ crate on [crates.io](https://crates.io) (and a few on
-GitHub). It is mainly used for checking the extent of breakage when implementing
+running tests for _every_ crate on [crates.io](https://crates.io) (and a few on GitHub).
+It is mainly used for checking the extent of breakage when implementing
 potentially breaking changes and ensuring lack of breakage by running beta vs
 stable compiler versions.
 
 ## When to run Crater
 
 You should request a Crater run if your PR makes large changes to the compiler
-or could cause breakage. If you are unsure, feel free to ask your PR's reviewer.

 ## Requesting Crater Runs
 
 The Rust team maintains a few machines that can be used for Crater runs
-on the changes introduced by a PR. If your PR needs a Crater run, leave a
-comment for the triage team in the PR thread. Please inform the team whether you
-require a "check-only" Crater run, a "build only" Crater run, or a
-"build-and-test" Crater run. The difference is primarily in time;
-if you're not sure, go for the build-and-test run. If
-making changes that will only have an effect at compile-time (e.g., implementing
-a new trait), then you only need a check run.
-
-Your PR will be enqueued by the triage team and the results will be posted when
-they are ready. Check runs will take around ~3-4 days, and the other two taking
-5-6 days on average.
-
-While Crater is really useful, it is also important to be aware of a few
-caveats:
-
-- Not all code is on crates.io! There is a lot of code in repos on GitHub and
-  elsewhere. Also, companies may not wish to publish their code. Thus, a
-  successful Crater run does not mean there will be no
