+# Example backend Dockerfile
+
+This Dockerfile will build the example backend with certain additional binaries needed to workaround
+the docker requirement in the scaffolder and techdocs.
+
+# Usage
+
+```bash
+yarn docker-build -f <absolute_path_to_the_dockerfile> --tag <your_tag>
+```
+
+> The absolute path is necessary as this directory is not copied to the build workspace when building
+> the docker image.
