Step 1: Make sure Linux is enabled. To enable Linux, "Open Settings/Linux (Beta)". When you are inside that folder, Click "Turn On", and now, it will download and install the Virtual Machine. Depending on how bloated your Chromebook is, It will probably take a good 5-30 minutes.
Step 2: Open Terminal. If this app did not launch, open the Launcher, scroll down, and then click Linux Apps. After that, you should see a new application called Terminal.
Step 3: Create an account. Depending on your e-mail address, your username will vary. My username is "tristan4@penguin". the first part is your email, and the @penguin bit is basically how it registers usernames.
Step 4: Install an app. Wait for the terminal to load, ("[=====]"), and then type "sudo apt-get install PACKAGE" Of course, replacing PACKAGE with the package name. Make sure to verify that it is a valid Debian package, otherwise it won't install. For example, to install Audacity, type "sudo apt-get install audacity"
Step 5: To remove a program (Like Audacity) type "sudo apt-get remove PACKAGE", again replacing PACKAGE with your package.
