Here's the google doc we've been using. This contains scripts for all the chapters in column C. Cell C1 contains the translation guide (i.e. how to use the scripts).
The doc also contains trello links so sign up and join the team. The trello board is where most of the work will be completed from now on. You can worry about it later though.
I've improved since starting out on this project so I'll be going back eventually to help out as well.
