+===== WARNING =====
+The current user doesn't have write permissions for
+the configuration dir ($CONF_DIR) or logs dir ($LOGS_DIR).
+It's likely that services will fail due to this.
+
+This is usually caused by cloning the repository as root,
+so the files are owned by root (uid 0).
+
+To resolve this, you can set the ownership of the
+configuration directory with the command on the host machine.
+Note that if the files are owned as root, the ownership must
+be changed as root (hence sudo).
+
+$ sudo chown -R $(id -u):$(id -g) /path/to$CONF_DIR /path/to$LOGS_DIR
+
+Alternatively, you can set the DOCKER_USER environment
+variable (on the host machine) to "root", though this
+isn't recommended.
+
+$ DOCKER_USER=root docker-compose up -d
