#8 mentions "Appendix B", which specifies STV rules. Once that's merged, we should add in the relevant appendix.

Initially assigning per discussion yesterday, feel free to reassign.

@adambirtles @sersorrel how likely is it that this will be ready by next Friday? No worries if not, just that it'll have to go to the next AGM (which is completely fine).

[adambirtles]

I'm working on this now. I should be able to make a PR later today or tomorrow.
