 Dockerised Cronicle, based on the [Cronicle-Edge](https://github.com/cronicle-edge/cronicle-edge) fork.
 
-Can function in both the **master** and **worker** role.
+Can function in both the **manager** and **worker** role.
 
 ## Running 
+
+`config.json`, located in `/config/config.json`, is automatically generated on the first run of Cronicle in 'manager' mode. This file must be kept identical between the manager and any workers it controls.
+
+NOTE: You need to define the hostname of the container if using `docker run`. Cronicle expects the hostname to remain the same, so the randomly-generated container hostname can cause problems if it changes. Docker Compose containers inherit their hostname from the `container_name` parameter, but it can also be defined using `hostname: xyz`.
+
