This is extremely simple. Just select, copy, and paste. If you do not know how to do this, I will explain to the best of my ability.

All you do is click on the button to the left on your mouse. Then drag the it down the page until all of the code is highlighted. Press the button on the right, go down the list and select "Copy"and click on it, making sure that the text is still highlighted as you do this. Next, edit your fanfic page and paste this code somewhere near the bottom. To paste, click on the right button and select the option "paste". If you can not put this on your fanfic page right away, open some kind of text file and save it for later use.
