When you joined the Church, you received two ordinances—baptism and confirmation. Likewise, the temple endowment is also received in two parts:

In the first part, you will privately and individually receive preliminary ordinances called the initiatory ordinances. The initiatory ordinances include special blessings regarding your divine heritage and potential. As part of these ordinances, you will also be authorized to wear the sacred temple garment.

In the second part, you will receive the remainder of your endowment in a group setting along with others who are attending the temple. During this part, the plan of salvation is presented, including the Creation of the world, the Fall of Adam and Eve, the Atonement of Jesus Christ, the Apostasy, and the Restoration, as well as instruction on the way all people can return to the presence of the Lord. Some of the endowment is presented through video and some by temple officiators.
