-Anyone can apply a label to issues.
+This command lets anyone apply labels to issues. This is most useful when opening an issue. In general, labels get applied to issues by the Triage WG. If you are interested in helping triaging issues, see the [Triage WG procedure](../../release/triage-procedure.md).

 @rustbot modify labels: +T-lang and -T-compiler
-@rustbot modify labels to +T-lang and -T-compiler
+@rustbot modify labels to +T-lang -T-compiler

 Note that the command can either terminate with a `.` or a newline, otherwise the bot will not parse the command successfully.
