+# docker-compose.yml — GitHub Actions self-hosted runner orchestration.
+#
+# All configuration is injected via environment files:
+#   - .env           → shared config (GITHUB_PAT)
+#   - envs/augur.env → per-repo config (identity, labels, resource limits)
+#
+# Quick start:
+#   cp .env.example .env && cp envs/augur.env.example envs/augur.env
+#   # Edit both files with your values
+#   docker compose up -d
+#
+# To add another repo: copy envs/augur.env.example to envs/<repo>.env,
+# fill in values, and add a matching service block below.
