+
+When not building one of the above distros, please use docker or some chroot.
+
+This repo contains an example Ubuntu container.
+
+$ cd docker
+$ docker build --build-arg UID=$(id -u) -t yocto_builder .
+$ docker run -it -v /path/to/yocto-rpi-example:/home/builder/yocto yocto_builder
+container$ cd /home/builder/yocto/
+
+Building
+--------
+
+Open init.sh and set MACHINE either to raspberrypi4-64 or raspberrypi3-64.
+Other variants should work too, but are untested.
+
+Source the init.sh script and use bitbake
+
+$ . init.sh
+$ bitbake its-image
+
+The final image will be tmp/deploy/images/raspberrypi4-64/its-image-raspberrypi4-64.wic.bz2
+
+You can flash it into you SDCard using dd. e.g
+$ bzcat its-image-raspberrypi4-64.wic.bz2 | dd of=/dev/mmcblk0 bs=32M
