 You can just drop a file called `setup` on the boot partition. When the installer notices that file at `/boot/setup`, it will automatically execute it using bash when installation finishes.

+### How to build pi64 from source?
+
+If you feel adventurous and want to build pi64 from source, you can easily do so through Docker.
+
+This is mostly useful if you want to make a custom Kernel build or want to tweak the distribution to your needs.
+
+To proceed with the build, run the following command :
+
+    docker build -t pi64 .
+
+Then you can build an image of the lite or desktop version :
+
+    docker run -it --privileged -v $PWD:/root/pi64 -v /opt/vc:/opt/vc  -w /root/pi64 \
+        pi64 make build/pi64-lite.img
+
+    docker run -it --privileged -v $PWD:/root/pi64 -v /opt/vc:/opt/vc  -w /root/pi64 \
+        pi64 make build/pi64-desktop.img
+
+The image will appear under the `./build` folder.
