+Portage Overlay Maintenance
+===========================
+
+This container allows for easy maintenance of a Portage overlay on a
+non-Gentoo system.  It sets up a Gentoo container, pulls in an overlay, and
+adds a few tools to facilitate maintenance.  It's set up to work with my
+overlay, but editing the Dockerfile should allow you to work with any
+overlay you want.
+
+Copy the SSH keys you need to access your Git repo into the ssh-keys
+directory, then set it up with ```docker compose up -d```.  Enter the
+running container with ``docker exec -it gentoo bash -l```.
