+Warning, you need a 64bit OS:
+
+If building on the Pi, you will also need a large swap (2 GB+)
+and reduce GPU memory to a minimum (e.g. 16 MB) using `raspi-config`
+(and reboot) before starting the build:
+
+You can use e.g. '`make -j4`' to speed up the build, but on a Pi 3 with 1GB memory you will likely
+run out of memory at some point and need to run the build again.
+Still, this can be faster if your build is attended.
