If you want to be able to preview your new page before you submit it, and are

willing to add a bit of extra complexity, you have to create a new branch

called `gh-pages`. Adding this branch will let you preview the whole site, so

you can see how your page will look when it is published (which is different

from the markdown preview that you will see on GitHub). To do this, click the

box where it says "branch: master". It should expand to show you a text box.

Type the text `gh-pages` in to the box that appears (make sure that it is

exactly that text; this is important). It should give you the option to create

a new branch; click that button.

Now, you should be able to navigate to

`http://<username>.github.io/ev3dev.github.io` in a new tab to see your copy of

the site. After you complete step 3, visit this preview URL again to make sure

that your page looks as it should.

If you complete this step, note that everywhere it says "`master`" in the

screenshots below, it should say "`gh-pages`" instead.

*WARNING*: If you complete this step, GitHub will send you emails warning you

about the CNAME. You can ignore them; but if they get annoying, see [the readme]

on the official site repo for information on circumventing the problem.
