Also, there are two versions of Lightroom. Lightroom Classic is what most of the tutorials are for. Lightroom 5.1 is a port of the mobile operating systems (i.e. iOS and android) to dektop operating systems and stores all your images in the cloud. CLassic stores all the images on your local computer. It is a different program. To add to the confusion, the CC moniker was used for both the predecessor of Classic and for the predecessor of the cloud program. Make sure you have what fits your work style best as they are completely different beasts.
