-## Buildpacks
-
-You can use [`buildpacks`](https://buildpacks.io) instead of `docker` by setting `use` to `buildpacks` on your config:
-
-```yaml
-# .goreleaser.yaml
-dockers:
-  -
-    image_templates:
-    - "myuser/myimage"
-    use: buildpacks

-
-Also, you can use a custom buildpack on `build_flag_templates` if you want.
-By default, `gcr.io/buildpacks/builder:v1` will be used.

-dockers:
