+# Background
+
+The `write_file` function has wo parameters.
+
+* `path`: is a relative path from some project_root
+* `content`: is the content that should be written into the file
+
+## Usage
+
+This function should be given a rw bind mount for the root of a project.
+
+```sh
+docker run --rm \
+       --mount type=bind,source=$PWD,target=/project \
+       --entrypoint /app/result/bin/entrypoint \
