You have a bit to learn to get it back up and running, Google is your friend in this, I would start by searching for "configuring cleanflight", or better yet do yourself a favor and re-flash the board with Betaflight and you will find a lot more because CF is the rarely used fork of the Baseflight code that started with the separation into CF and BF. BF gets better stuff sooner because many more people are working on it than CF and by far many more people are using BF than CF. But either way they are essentially identical as far as 99% of the configuration so you could also watch vids about BF as well as CF. I would recommend you look for stuff from Project Blue Falcon or Joshua Bardwell, even though it is BF based, CF is almost, if not identical.
