+## 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).
-
-Here's a minimal example:
-
-```dockerfile
-ARG pg_graphql_release=1.1.0
-
-####################
-# 19-pg_graphql.yml
-####################
-FROM base as pg_graphql
-# Download package archive
-ARG pg_graphql_release
-ADD "https://github.com/supabase/pg_graphql/releases/download/v${pg_graphql_release}/pg_graphql-v${pg_graphql_release}-pg${postgresql_major}-${TARGETARCH}-linux-gnu.deb" \
-    /tmp/pg_graphql.deb
-
-####################
-# Collect extension packages
-####################
-FROM scratch as extensions
-COPY --from=pg_graphql /tmp/*.deb /tmp/
-```
-
-Using this process maximises the effectiveness of Docker layer caching, which significantly speeds up our CI builds.
