LOL god bless computers!
The next step will be to set your key configs.
That is a decision you have to make based on how you want to use the machine, which emu's etc etc.
Once you have decided that program the device accordingly and then install all your software.
If you dont know which emus etc require which controls look that up first.
Once all installed its the long task of configuring all the keys in each emu, setting up your front end etc.
