What does it mean to salt a steak? How much salt do you use? Do you salt both sides?

It means to season the steak on both sides with salt, as you would before cooking it. Sometimes recipes will instruct you to do this up to an hour in advance of cooking.
A few more details would be very helpful but the process is pretty simple. Cover both sides of the piece of meat with a light-to-medium sprinkling. Exactly how much depends upon the thickness of the steak and the type of salt you're using. Most chefs use kosher salt because it provides better control of how much you're applying (including being able to see what you're doing) but whatever you have at hand will suffice. Err on the side of too little!
