+# University of Oregon GitLab runners
+
+The UO runner fleet is described compactly in [`fleet.toml`](./fleet.toml). Each
+host's full gitlab-runner `config.toml` is produced from that source by
+[`generate.py`](./generate.py) — the boilerplate that is identical across every
+runner (docker/cache blocks, the pre-build bootstrap script, the session server)
+lives in the generator, so it is defined once instead of copied per runner.
+
+## Editing the fleet
+
+Edit `fleet.toml`. Per-host you set `concurrent` (and optionally
+`connection_max_age`); per-runner you set `name`, `id`, `limit`, and an optional
+`environment` list. Everything else is fleet-wide boilerplate baked into the
+templates in `generate.py`.
+
+## Generating configs to apply
+
+```bash
+# print one host's config, with the real token injected, ready to drop on the machine
+GITLAB_TOKEN=glrt-xxxx python3 generate.py --host athena --stdout
+
+# write every <host>.config.toml into this directory (uses the %%GITLAB_TOKEN%% placeholder)
+python3 generate.py
+
+# write one host to a specific location
+python3 generate.py --host athena --out-dir /etc/gitlab-runner
+```
+
+If `--token`/`$GITLAB_TOKEN` is not supplied the `token` field is left as the
+`%%GITLAB_TOKEN%%` placeholder, so a real token never has to live in the repo.
+
+The original per-host configs this source was derived from are kept for
+comparison under [`reference/`](./reference).
