+# 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 \
+       --workdir /project \
+       vonwig/findutils:latest '{"glob":"*.md"}' find "." "-name"
+```
+
+## Build
+
+```sh
+docker build -t vonwig/findutils:latest .
+```
+
+```sh
+# docker:command=build
+
+docker buildx build \
+    --builder hydrobuild \
