Tl; drLegal is an abbreviation of too long; Did not read.
The task of the site is to give a human-understandable description of the instructions for the licensed software.
Well, the truth is, you pay money and do not know your rights and limitations.

Generally it would be nice to first learn and then buy.

Registration is required, but without registration you can see - look.
If you bring a program, get a bunch of links, this license is broken down into points, because we do not need to study the instruction, and learn a couple of paragraphs, the site helps to find them.
