It is rough but there is a list of TODO items for the User Guide at https://fedoraproject.org/wiki/User:Laubersm/F13_UG_Update_Checklist

For most chapters someone just needs to sit down in front of an F13 system and check for glaring changes. Small chunks of easy work - feel free to grab one (or three).

I am continuing work on the Office Suites Chapter - after some sleep.... I'll be in fedora-docs tomorrow. Lots of other people there can probably help fill in the blanks on how to accomplish the TODO items.

Thanks, -Susan
