Note this is for advanced users. The simplest way to install/setup PiAware is by using the image-based SD card install. See the PiAware 3 announcement thread.
If you would like to do a package-based install of PiAware on an existing Raspberry Pi, you may now do so. The instructions for a package-based install are available on our PiAware Installation page.
(If you are interested in PiAware 2 in-place upgrades, we will have an announcement about that option in the coming days.)
Thanks for your interest in PiAware!
