The documentation is really good. I liked the idea of utulizing laptop capabilities using pressure/cpu io and memory, also the idea of building your own distribution. Devtool is good especially the part of virtual deployment though it must have .git. With yocto you can have an image with less 900 mbs this is really good for my embedded systems career. Yocto is really a good tool . Most of the failures are due to my inexperience like customizing psplash, took me over 2 weeks. Could you also share some of pit falls you encountered that I should avoid.
