+Work In Progress Patches
+========================
+
+- Multiple ways a patch can be indicated as a Work In Progress
+
+  - 'Workflow' is set to '-1'
+  - '[WIP]' is at the beginning of the patch's summary line
+
+- Developers often do this to share an early preview of what they are
+  doing or to allow for feedback during development
+- Patches may be reviewed but should be done so with the fact that
+  the patch is still being developed in mind
+
+  - Don't -1 for spelling mistakes, wording or missing details
