The easiest way to add software to your system is by using our AppCenter.
The AppCenter is an online service Bodhi provides, where you will be able to find all sorts of software to spice up your new system.
We also provide Synaptic and apt for installing a wealth of software from Ubuntu's and our own repositories.
Still need that one bit of software you can't find in our collection? Ask in our forum and we will add it for you!
