+Pinakes, despite all the work going into it, is still in an early beta. Some of
+the features still lack the polish they deserve and there _may_ be breaking
+changes to the UI, databases, and the APIs. You may find a comprehensive
+introduction to developing Pinakes in the [HACKING document].
+
+It is generally advisable that you familiarize yourself with the codebase before
+proposing or contributing changes. Pinakes consists of _many_ moving parts, and
+it is better for the contributor experience to approach issues slowly and
+discuss them beforehand.
