Once you’ve created a tournament or league, you can add players to it.
(Typically you want to create events first so that when you add a player, you can also add them to the events they are participating in.)
First navigate to the relevant tournament or league, and you’ll see the Player options up top.

Here you have the following options:
Search Players
This allows you to add or edit a player by searching for their name or Member ID. If they exist within the membership system for this tournament or league, they should show up here.
New Player
Without Member ID
Add a new player who does not yet have an ID within your membership system.
With Member ID
For some reason, if you cannot find the player via Search but know their Member ID, use this option to manually create them from their Member ID.
