+Core Development Rules
+======================
+
+All incoming changes need to be acked by 2 different members of Hylang's
+core team. Additional review is clearly welcome, but we need a minimum of
+2 signoffs for any change.
+
+If a core member is sending in a PR, please find 2 core members that don't
+include them PR submitter. The idea here is that one can work with the PR
+author, and a second acks the entire change set.
