checked in for the day, you can find the last-working build tag on the branch you care about, and branch from that point. +There will be frequent exceptions. Try not to violate this rule too often, and if you do, feel a little bit guilty about it. + {subsection: Document the branch name} You must add a description of the new branch {wiki: GitBranchDescriptions here}. The description should include the name of the person who created or is responsible for the branch, the date, where the new branch came from, what it is for, and any plans for when/where it's going to be merged back into (if we know them).
