If you have a new concrete floor then it'll be easy to lay. Get knee pads. They cost under €20 and you'll save yourself some serious pain. As noted above YouTube is your friend. The trick with the block and double sided tape to close any gaps works really well. The secret when laying it (it's all click together now) is to tap the side of the board to make sure it is seated properly before you tap the end to move it down to meet the previous board. You'll know what I mean when you start. Oh, and use the plastic block you get in the installation kit. It really is very easy.
