Wow. Next time I tell someone to rtfm, I can give them a link to teach them how. Very good general start though.

Don't foget about ls -a. The -a option gives you the ability to list all files, including the hidden ones, in the directory. This can be very useful sometimes. Especially when you mistype something like mkdir .directory And create a hidden directory by accident. For those who don't know, and file/directory that starts with a . (period) is hidden.

One other thing that might be helpful for you MsMittens. Although many people in here are Windows people, a lot of them still know dos. A quick reference to the equivalent dos command can be very helpful, unless you wanted to do a quick reference tutorial also. ie:
clear cls Used to clear the screen..........

I made a quick reference sheet for a class once, and the other students at least clamed that it was helpful.

It looks like you are off to a good start though MsMittens. Keep it up.
