+# Docker image for DCO checks
+
+This image provides the environment and the logic of running a DCO check
+against a repository.
+
+## Configuration
+
+The `entrypoint.sh` script assumes at runtime that the repository to be checked
+is available under `/work`. This path is to be populated via bind mounts when
+running the container.
