+The configuration is a normal text file living in `~/.config/dash/`.
+You can use it to take notes or display the output of shell commands via the `{command args}` syntax.
+The output can be piped to other commands, e.g. `{pacman -Q | wc -l} packages installed`.

 If you're using alacritty you can set the opacity for a single instance via:
 
 ```sh
 alacritty msg config window.opacity=0.5
 ```
+
+This will make your dashboard transparent but leaves the other windows at full transparency.
