The build process is structured around groups of recipes written using a combination of Python and shell script. The Yocto Project includes a task scheduler called BitBake that produces whatever you have configured from the recipes. There is plenty of online documentation at https://www.yoctoproject.org/.
Background
The structure of The Yocto Project makes more sense if you look at the background first. Its roots are in OpenEmbedded (https://openembedded.org), which grew out of a number of projects to port Linux to various hand-held computers, including the Sharp Zaurus and the Compaq iPAQ. OpenEmbedded came to life in 2003 as the build system for those hand-held computers. Soon after, other developers...
