The most common styles of tents are pop-up tents and teepees or other tents that make use of poles. Many pop-up tents don't require any assembly. You take it out of the box, unfold it, and set it on a flat area. These come down as easily as they can be set up. Teepees and other tents that require assembly usually have poles of some kind. You may need to attach the poles or they may come already assembled. Then, you thread them through the fabric and pull the tent up. In most cases, manufacturers include instructions for assembling the tent.
