 Dokku normally defaults to using [Heroku buildpacks](https://devcenter.heroku.com/articles/buildpacks) for deployment, though this may be overridden by committing a valid `Dockerfile` to the root of your repository and pushing the repository to your Dokku installation.

+### Allowing herokuish for non-amd64 platforms
+
+> New as of 0.29.0
+
+By default, the builder-herokuish plugin is not enabled for non-amd64 platforms, and attempting to use it is blocked. This is because the majority of buildpacks are not cross-platform compatible, and thus building apps will either be considerably slower - due to emulating the amd64 platform - or won't work - due to building amd64 packages on arm/arm64 platforms.
+
+To force-enable herokuish on non-amd64 platforms, the `allowed` property can be set via `builder-herokuish:set`. The default value depends on the host platform architecture (`true` on amd64, `false` otherwise).
+
+```shell
+dokku builder-herokuish:set node-js-app allowed true
+```
+
+The default value may be set by passing an empty value for the option:
+
+```shell
+dokku builder-herokuish:set node-js-app allowed
+```
+
+The `allowed` property can also be set globally. The global default is platform-dependent, and the global value is used when no app-specific value is set.
+
+```shell
+dokku builder-herokuish:set --global allowed true
+```
+
+The default value may be set by passing an empty value for the option.
+
+```shell
+dokku builder-herokuish:set --global allowed
+```
