-    context -> comment (str)
+"""Collect comment and add option to enter comment per instance.
+
+Combination of plugins. One define optional input for instances in Publisher
+UI (CollectInstanceCommentDef) and second cares that each instance during
+collection has available "comment" key in data (CollectComment).
+
+Plugin 'CollectInstanceCommentDef' define "comment" attribute which won't be
+filled with any value if instance does not match families filter or when
+plugin is disabled.
+
+Plugin 'CollectComment' makes sure that each instance in context has
+available "comment" key in data which can be set to 'str' or 'None' if is not
+set.
+- In case instance already has filled comment the plugin's logic is skipped
+- The comment is always set and value should be always 'str' even if is empty
+
+Why are separated:
+- 'CollectInstanceCommentDef' can have specific settings to show comment
+    attribute only to defined families in publisher UI
+- 'CollectComment' will run all the time
+
+Todos:
+    The comment per instance is not sent via farm.
