+## Review Board
+
+For very large and complicated Pull Requests we have created a Review Board instance to facilitate more in depth review and discussion at https://review.openprivacy.ca
+
+First acquire the client, RBTools, on Ubuntu:
+
+    apt install rbtools
+
+Then hookup your git repo to review board with:    
+
+    rbt setup-repo
+
+Using the repo `cwtch`
+
+Finally you will be able to create commits with
+
+    rbt post --parent master
+
+It possibly will need the arguments `--tracking-branch=cwtch/master --branch=YOUR-BRANCH -d` (-d for debug if you are having trouble)
