+## Admin API
+
+The relay has a number of admin HTTP API endpoints. Given a relay setup listening on port 2470 and with a reasonably secure admin secret:
+
+```
+RELAY_ADMIN_PASSWORD=$(openssl rand --hex 16)
+bigsky  --api-listen :2470 --admin-key ${RELAY_ADMIN_PASSWORD} ...
+```
+
+One can, for example, begin compaction of all repos
+
+```
+curl -H 'Authorization: Bearer '${RELAY_ADMIN_PASSWORD} -H 'Content-Type: application/x-www-form-urlencoded' --data '' http://127.0.0.1:2470/admin/repo/compactAll
+```
