+## Adding a New Extension
 
-Extensions can either be built from source or installed through a debian package. In general, you want to add the installation commands for your extension to the [Dockerfile](Dockerfile) following the steps below.
+Supabase Postgres supports multiple Dockerfiles for different versions and deployment scenarios (e.g., `Dockerfile-15`, `Dockerfile-17`, `Dockerfile-kubernetes`, `Dockerfile-orioledb-17`).  
 
-1. Create a [build stage](Dockerfile#L777) named after your extension.
-2. Add build args that specify the extension's [release version](Dockerfile#L37).
-3. If your extension is published as a package, download it to `/tmp/<name>.deb` using the [ADD command](Dockerfile#L705).
-4. If you need to build the extensions from source, use [checkinstall](Dockerfile#L791) to create a `/tmp/<name>.deb` package.
-5. Copy your extension's package from build stage to [extensions stage](Dockerfile#L851).
