+# `admin`
+
+Bunch of scripts I use to administrate the rkgk instance at <https://rkgk.app>.
+The full setup is:
+
+- A systemd service runs `daemon.bash` in a separate user.
+  - This script builds and runs the server.
+  - It also listens for `reload` commands being sent through a FIFO, which can be used to make the server rebuild and rerun.
+- The `reload` command is sent by the `deploy.bash` script which runs on my own machine rather than the server.
+  - This script causes a `git pull` and a `reload` command to be run.
+
+This is more or less the same setup as <https://liquidex.house>.
