That should work, you might want to add a link to "abp:subscribe?location=h||ps://raw.githubusercontent.com/paulgb/BarbBlock/master/BarbBlock.txt&title=BarbBlock" in your readme to allow people to easily install the list by clicking that link. Edit: replaced https with h||ps to prevent it from showing up as a link (which are apparently cut off if they're too long).
