To the anon; you use the code, under each paragraph. If you want it like Ellie's, then you put under the paragraph and then put your next under it. I hope this helps. (Also hope this shows up in the ask? The code I mean? xD)
Nonnie, did this answer your question?
So basically if you want a double-space (like between the first and second lines of my description), you just put [p]text here[/p], except those arrow things instead of brackets.
For a single space (like between the second and third lines of my description), you put a [br]text here[/br] instead.
Let me know if you have any other questions!
