After DYK hooks are approved, the nominations is closed and a hook is promoted to the prep areas, where it is scheduled and possibly workshopped. If you feel like doing that closing and promoting, this is the right place for you! Prep building, as it's called, is vital to keeping DYK's gears turning, and it allows experienced behind-the-scenes editors to exercise a little bit of quality control (in accordance with the wishes of the nominator and the community at large). This page will tell you what checks you need to make, and then walk you through the steps of promoting a hook.
If this is your first time promoting a hook, welcome to the fold! Be sure to read WP:DYKPBR to get a sense of the promoter's guidelines. Don't be afraid to make mistakes when you're starting out, and WT:DYK is where you can get answers to all your questions about the process.
