Installing software in Ubuntu is really easy. Here's how.
First open the Ubuntu Software Centre
which will be in the dash and maybe on the launcher.
Then browse for the program you're looking for, or search if you know what it is called.
Double click on the program you want and click the install button
Type in your password when prompted
If you click on the progress tab at the top you'll be able to see the program downloading and installing
When it's done, search for it in the dash. There we go - your new program!
