+TL;DR: xref:qemu-buildroot-setup-getting-started[xrefstyle=full] tested on Ubuntu 24.04:
+
+....
+git clone https://github.com/cirosantilli/linux-kernel-module-cheat
+cd linux-kernel-module-cheat
+sudo apt install docker
+python3 -m venv .venv
+. .venv/bin/activate
+./setup
+./run-docker create
+./run-docker sh
+....
+
+This leaves you inside a Docker shell. Then inside Docker:
+
+....
+./build --download-dependencies qemu-buildroot
+./run
+....
+
+and you are now in a Linux userland shell running on QEMU with everything built fully from source.
