+# An entity is something that exists - a "thing", like a VM, or a Container

+# A very popular use case that entities were designed for was for `container`
+# entities - in a similar way you could generate `start`, `stop`, and `restart`
+# container actions.

+# Entities are just loaded fome files on disk, OliveTin will also watch these
+# files for updates while OliveTin is running, and update entities.
