+# Polybar configuration
+
+![](bar.png)
+
+To be able to put my config in Git and keep some stuff I don't want to share confidential (my MPD server host and password), I created a `secrets.sh` file. Mine looks like this:
+
+```sh
+#!/bin/false
+
+MPD_ONLINE_1_HOST=mpd.example.org
+MPD_ONLINE_1_PORT=6600
+MPD_ONLINE_1_PASS=mypass1
+
+MPD_ONLINE_2_HOST=mpd2.example.org
+MPD_ONLINE_2_PORT=1234
+MPD_ONLINE_2_PASS=mypass2
+```
