Note
Yamlld will soon be deprecated for a much larger project
Yamlld is a busybox based Linux distro based on Yosild with many improvements to it, including UEFI/Legacy support, installation guide, dpkg, newer kernel, new FS support, and many more things.
It's compatible with 32 and 64bit, and is very lightweight.
Copy a prebuilt kernel into the same directory as Yamlld under the name bzImage. Then, run sudo bash yamlld.sh.
