Modifying the PATH variable
Before you issue commands to OUYA from your command line or terminal, you'll need to make sure your system recognizes those commands. To do this, you'll be editing your PATH variable to include the location of the Android SDK you downloaded.
Note
The PATH variable is a string of directory locations, or paths, that your command line looks through when it's checking for commands. Any commands in directories that are included in your PATH variable can be run from any working directory instead of having to be run from the folder they're stored in.
Mac OS and Windows both have PATH variables, but they're edited differently; the upcoming tutorials will cover both the operations step by step.
