2. Create initial groups - Goosly/AGE GitHub Wiki
Originally AGE was built for the approach where all competitors compete in one group and then help judge, run or scramble for another group in the same round. More options were added later, to allow for more customization of the generated groups.
For every event, you can choose the number of scramblegroups and stages you want to use. If you pick the option with staffing, you will also be asked to for the number of runners and scramblers you would like to have (or you can leave this at the default number).
Scramblers and runners are picked randomly from a list you provide in a CSV file. AGE provides a template for such a CSV file. If you don't care to much about these scramblers and runners, you can simply let AGE pick them for you.
I highly recommend playing around with all options. You can always start from scratch by reloading the site - press F5 on your keyboard.
