-- **feature** - new end user functionality, available sublabels for estimates:
-  - **estimate/hours**, **estimate/days**, **estimate/weeks** - ballpark estimate for feature
-- **bug** - broken end use or developer functionality; not working as the developers intended it, available sublabels for priority:
-  - **bug/P0** - Urgent issue that caused someone to be paged, must be updated hourly
-  - **bug/P1** - High impact issue, must be updated daily, must be resolved before resuming milestone work
-  - **bug/P2** - Issue is affecting users, should be resolved before resuming milestone work
+- **feature** - new end user functionality
