OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "nodistro") and contains only emulated machine support.

The Yocto Project has extensive documentation about OE including a reference manual which can be found at: https://docs.yoctoproject.org/
