How to install pocket door?

A pocket door is a sliding door that, when fully open, disappears into a compartment in the adjacent wall. Pocket doors are used for architectural effect, or when there is no room for the swing of a hinged door. They can travel on rollers suspended from an overhead track or tracks or guides along the floor. Single- and double-door versions are used, depending on how wide an entry is desired.
