Hi Katherine. This is your own test page. You can do whatever you want to it, as you learn WordPress. I have added some text below using “ShortCodes”, which are special codes in square brackets. The particular codes create columns of text, which in my opinion are easier to read.
You can add media by clicking the Add Media button above. This one is aligned right. It doesn’t actually appear correctly in the editor with the ShortCodes.
CLick the Preview Changes button at the top right to see how it will look.
