 When you make significant changes, you can bump the major or minor
 number yourself with `thor version:bump minor`. This will create a tag
 with a .0 patch level, so the next build made by the server will be
 .1 patch level.

+### Auto bumping
+
+If you include #major or #minor in the subject of commits, and run
+`thor version:bump auto` it will see if any major or minor level changes
+are included since the last tag, and use the appropriate version. This works
+especially well with a CI server, allowing you to never have to directly
+manage versions at all.
