Hullo! I think it's a blockquote you're after. You do this.

<blockquote>Then type all the text you wanted indented in here and then end it with a backslash blockquote like this</blockquote>

If it works

It should look like this and be nicely separated from the rest of the text and it's up to you if you want to put a line between the main text and the quoted text

Hope that helps!
