I don't kno how to use layouts at all. They confuse the crap out of me

If the profile layout is from the market place, you have to ask the designers for the code because at the moment, we can only install them in descriptions, forewords and story chapters.

Likewise, if the profile layout is from a shop here, all you have to do is ask the designer. He/she will give you a code. Go to your text editor, click the very first icon in the toolbar called source which looks like a notepad. Paste the code. Then edit it with your own information. Replace photos. Save.
