-## Building the Extension
-
-The "build" process for this extension involves packaging the extension's
-metadata files (`gemini-extension.json`, `cloud-sql-postgresql.md`, `LICENSE`) along with the
-pre-built `toolbox` binary into platform-specific archives (`.tar.gz` or `.zip`).
-
-This process is handled automatically by the

-GitHub Actions workflow when a new release is created. Manual building is not
-required.
