Huw's comments on Branches.md

[Huw Davies]

-Maybe tidy the readme up a little with some markdown so it's more readable- titles, bold, italics
-'Branch is a thing' in first line could be phrased a little differently
-'To create a branch type -' is confusing. I thought you were asking the user to type '-'.
-There's also a lonely '<' before git branch
-You could create a nested set of bulletpoints after the bulletpoint: 'You should always branch if'
-There's also a bit at the bottom surrounded by ??? which I'm not sure is meant to be there

Other than that, great!
