+This is a tiny proc\_macro crate that provides attribute macros for gazelle. The macros return their
 inputs unchanged, and exist only to pass information to gazelle. The attributes are also referred to
 as "directives".
 
 An alternative would be for gazelle to parse special comments. Using the attribute is nicer in some
 ways: it allows more direct control over which items should be affected by a particular directive,
 and it's easier to integrate into the existing syn-based parser.
 
-This crate has a cargo-compatible directory structure so that in the future it can be published on

+This crate has a cargo-compatible directory because it is also published to crates.io to support
+projects that build both with bazel and cargo.
+
+Since crates.io has a global namespace, this is the one and only "gazelle" package. Please reach out
+to me if you're working on an alternative gazelle plugin for Rust, I'm happy to make changes as long
+as backwards-compatibility is maintained.
