Start by running

$ wfsports start names.csv

This outputs a file called round1.csv. Each row of this file has the names of two players competing in this round. As the organizer, you get to add the name of the winner to each of the rows once the round is done. If the number of players isn't a power of two, there will be some players who get a free pass to go to the next round. They will show up in rows like Alice,Alice,Alice, meaning that Alice has played against her self and won.

After entering the winners in round1.csv, run

$ wfsports next round1.csv

That will make random pairs of winners from round 1 and output round2.csv in the same format as round1.csv. Once they play each other, you as the organizer get to add the winners' names as in round1, and repeat running wfsports next round2.csv and repeat the process until someone wins the whole tournament.

To display the players for round N on the projector, run this (on Mac):

$ wfsports show roundN.csv
$ open table.html

Start by running the following:

$ for i in $(seq 10); do wfsports -outround=$i start names.csv; done
wrote round1.csv
wrote round2.csv
...
wrote round10.csv

Then play round 1 according to round1.csv, recording the winners to round1.csv. Then play round 2 according to round1.csv, recording the winners to round2.csv. ... up to round 10. Then run

wfsports startfinals

which will generate round11.csv. Play round 11, record the winners to round11.csv, then run

wfsports next round11.csv

and proceed as before for single elimination.
