+### Find the implementation
+
+Choose **Code** in the **All files** filters to search source files. Look up a
+symbol you know, or describe the behavior you need. Local Google embeddings
+help connect your description to an implementation; the preview preserves code
+formatting and shows the source passage's starting line.
+
+Rust, Python, JavaScript/TypeScript, C/C++, Go, Java, C#, Swift, SQL and many
+other source formats are supported, including named build files such as
+`Makefile` and `Dockerfile`. Add your project folder and let semantic indexing
+finish for meaning-based search. See [code search](docs/CODE-SEARCH.md) for
+details and agent integration.
