+    Plugins may use two types of special values, stored in two dicts: runtime
+    values and storage values. Runtime values can be accessed by other plugins
+    to get information about the runtime state of the bot. Currently it is used
+    to store if the bot is asleep or awake by the sleep plugin, and its current
+    mood by the mood plugin. They are lost when the bot shuts down. Storage
+    values on the other hand are written in a storage file everytime the object
+    is modified during runtime and also when the bot shuts down. Storage values
+    are stored as JSON, so values must be JSON-encodable. Storage values should
+    be used everytime information needs to persist over restarts instead of
+    external files. Access here means read and write, for both runtime and
+    storage values.
+
     Plugins can have priorities and calling their callbacks will respect it.
     For now these levels are used:
