To add players, tap on the "+" button adjacent to the "Players" heading.  There are three ways to add players.  First you can select them from a list of recent playing partners (easiest).  This list gets populated as you create more events.  Since this is our first event, there are no players in the list yet.

Since this is our first event, there are no players in the list yet so we have two options, first we can "search" (by name) for players that we have played with before or we can "invite" new players to Marker.  For this example, we'll use the "search" function first.

Type into the "search" bar to find any previous playing parnters by name.  We'll add ourself first by typing in "bart" and selecting the result.

We could continue to add players here, for now we'll just click continue and then we'll select the tees for the event.  (Tees can be individually changed on the scorecards if players wish to play from other than the default setting.)

We select the tees for the event.  This selection will be the default for any additional players added while configuring the event.  Tap "Save" and the player(s) will be added to the event roster.

We can also "Invite" a player to the game.  Tap the "Invite new player" button.

Enter the player's phone number, if they are already a Marker user, their information will get populated automatically.

You can see the default tees are preslected so you can just tap "Save" and this user will be added to the event. 

I have gone through and added a few more users for our example.  Once we have all the users added, we move on to creating the scorecards for the groups.
