+## Sequence of outcomes
+
+Nothing can be achieved immediately and everything takes time. If we
+follow from the principle of "start with what we do now" and "do the
+easiest next thing to improve", the below is a potential sequence of
+outcomes to get to where we'd like to be. These are in order of what
+we'd like to achieve first to last, focusing on achieving one outcome at
+a time.

+### Collaboration
+
+1.  Only use GitHub Issues for tasks, discussions, and general
+    communication, so that all work is visible and tracked in one place.
+2.  Always refer to the GitHub Project board for the current status of
+    the project or individual work packages, so everyone is aware of the
+    current state of things.
+3.  Only use Discord for communication
