+## Use Cases
+
+There are several potential use cases:
+
+* **self-review**: upload a change just to double check the handy side-by-side
+ diffs
+* **pre-review**: you may do a pre-review within a team before sending the
+ change upstream for the official review; or use it for some preliminary design
+ discussions; or just keep track of progress and versioning
+* **complement the current review process**: include a link to the change
+ into the upstream patch email as FYI (maybe after "---" line); this preserves
+ the current process, but gives side-by-side diffs, full context,
+ version diffs, base commit, change tracking, etc
+
+Feel free to use it if you find it useful.
+
+**Note**: when you upload a new change nobody is notified. You can add
+reviewers/CC manually and/or give the change link to other people.
