+# tmate
+
+this repo holds
+* `docker-compose.yml` for our instance of [tmate](https://tmate.io)
+* `systemd` unit file to easily start/stop/manage the service
+* example tmate config to let clients make use of our instance
+
+> Note: commands below are to be run from the project folder
+
+#### server-side setup
+
+```sh
+mkdir -pv /etc/tmate
+cp -v docker-compose.yml /etc/tmate/
+cp -v tmate.service /etc/systemd/system/
+systemctl daemon-reload
+systemctl enable --now tmate.service
+```
+
+#### tmate client setup
+
+```sh
+if [ ! -f $HOME/.tmate.conf ]; then
+    cp -v example.tmate.conf $HOME/.tmate.conf
+else
+    printf " * file \"$HOME/.tmate.conf\" already present, not doing anything\n"
+fi
+```
+
+after you've got the config in place (and tmate installed locally), run `tmate`
