 # easyconf-lemonbar (eclb)
 
-A python script to easily configure lemonbar.
+A small python script to easily configure lemonbar. Uses a simple yaml file to
+declaratively define your custom bar, and includes useful features such as
+asynchronous refreshing and signal handling. Concept inspired by
+[UtkarshVerma/dwmblocks-async](https://github.com/UtkarshVerma/dwmblocks-async).
