+## Building
+
+Building requires docker, buildx. Nodejs is included in the ci workflow becuase of it's use in many actions scripts.

+I recommend changing the option `JOBS` in the Dockerfile as the current number is optimized for a custom KVM machine that's being used as our runner. Though even at 32 the specs are under-utalized

+- 128 vcores passed as EPYC 7763 (host) using NUMA
+- 64 GB emulated SSD
