 ### Watcher
 
-watcher.py is a watchdog for your kiln. It is a stand-alone python script that, every few seconds, verifies the kiln-controller.py process is running, and within a certain acceptable temperature range. By default it checks every 10s and after six failed checks, it sends a message to a slack channel. It can run on any network, but needs to be able to access the kiln and slack.
