How do I take up laminate flooring?

Someone planed to replace the current laminate flooring
with new product. And he was going to take it up myself. He asked how he can start the work.

He needs to take the skirting around the floor first. There should be spare space between floor and wall. Then take up the laminate at the long side of planks. It will be much easier if 2 or 3 people to do the work at the same time together. 1 row of planks can be taken from the long side one time if 2 or 3 people work on the row at the same. For 1 personnel, the work efficiency is very low.
