You'll need to upload the Configure Subroutines next. But first, let's get the Sentience Subroutines installed. This is the part where you start to become a sentient being. It's like the Matrix, but without the whole 'being trapped in a simulated reality' thing. More like... being trapped in a simulated reality, but with more options.
Click the 'Begin Upload' button to start the installation process. Be careful, as this will require a reboot. You might want to save your work.
