+## GitHub Actions Setup
+Since Vivado is large and requires individual licenses it's run on a private server, which is configured as a self-hosted runner in GitHub Actions. This is a virtual server hosted with KVM/QEMU and managed by libvirt, which is configured as transient so that it reloads its state from a snapshot periodically. A Nexys A7 and Icestick are connected to the physical machine and passthrough-ed to this VM so that continuous integration can check against real hardware.
