 <summary>Library usage</summary>
 
-`csp` is also a Rust library crate (`csp`, in [`crates/csp`](crates/csp)), useful when building custom tooling or integrating search directly into your own Rust code. It exposes `CspIndex` with `from_path` / `from_git` / `search` / `find_related`, plus the `ContentType` enum and the ranking pipeline.
+`csp` is also a Rust library crate, published on crates.io as [**`code-search-please`**](https://crates.io/crates/code-search-please) (the short name `csp` was already taken). The library name stays `csp`, so you depend on `code-search-please` but still write `use csp::...`. It exposes `CspIndex` with `from_path` / `from_git` / `search` / `find_related`, plus the `ContentType` enum and the ranking pipeline.
