How do i add different teams to my game?

So, i'm a newbie.. How do i add teams to my game? I saw a game where you can control the teams with admin, example:

:team [robloxusername] red :team [robloxusername] blue

How can i add this? If this is hard to make.. i have an another option

How do i add teams where you can touch a spawn.. example:

I touch the blue spawn, ill be team blue I touch the red spawn, ill be in team red

Go to the toolbox then type "blue team" then you should see a model made by roblox come up. There should be a folder now in the explorer called "Teams" in the folder you'll see a team. You can copy and paste that team and change it's team color to whatever you want. Then copy and paste the team spawn and make the team color whatever the team color of the team is that you made. Also check" "AllowTeamChangeOnTouch".
