A redirect is a special page that automatically causes the text of another page to be displayed in its place. A redirect that points to another redirect is called a double redirect. These pages are undesirable, because Wikipedia's MediaWiki software will not follow the second redirect, in order to prevent infinite loops. A self-redirect is an article that redirects to itself. These situations create slow, unpleasant experiences for the reader, waste server resources, and make the navigational structure of the site confusing.
Let's start off with the basics. You can make italics by putting in 2 of these(') before and after the word, in other words, I made the word italics italic by doing this ''italics''.

Finally, you can make bold italics by placing 5 's before and after the word or words, in other words, I made the bold italics bold and italic by doing this '''''bold italics'''''.
