Only half-serious, as opposed to 3/4 serious. Take of it what you will.

Update your gradle and mappings. Get it wrong because you forgot to add the branch name.
Commit so you feel good about taking the first step
Rerun setupDecompWorkspace, refresh Gradle project in your IDE.
Try to compile the mod and cry after seeing the error count
Easy renaming time. If a class (or method/field with distinct name) has been renamed, just do a global find/replace. Congrats, you just added 10000 lines to the diff. Commit.
Easy method signature time. If a method has changed arguments, say to add a hand parameter, just do a global find/replace. You DID name your parameters properly, not p_10101101010_xxx, right? ... Oho, you're going to have fun. Commit.
Easy semantic stuff. This is stuff like changing x y z args to BlockPos, ForgeDirection to EnumFacing, etc. Commit per change.
Missing methods. If something you override from vanilla is no longer there, first check the bot to see if it got renamed (!mh
