How do you add someone on league of legends?

Answer 1

At the bottom of your screen, from the home page in game, you will see a "friends menu" button. It will be the first (the one all the way to the left) of the three buttons. There are three person icons on it. Clicking this will bring up your friends list. At the bottom, right hand corner of your friends list is another person icon with + beside him. Clicking this will bring up a dialog box that asks you to type your friend's summoner name. Enter his/her name and then click the + beside the name. You must now wait until your friend accepts your request.
