 Run one command, get a QEMU Buildroot BusyBox virtual machine built from source with several minimal Linux kernel 4.14 module development example tutorials with GDB and KGDB debug and minimal QEMU educational models. "Tested" in x86, ARM and MIPS guests, Ubuntu 17.10 host.
 
+Reserve 12Gb of disk and run:
+
+    git clone https://github.com/cirosantilli/linux-kernel-module-cheat
+    cd linux-kernel-module-cheat
+    ./configure
+    ./build
+    ./run
+
+The first build will take a while ([GCC](https://stackoverflow.com/questions/10833672/buildroot-environment-with-host-toolchain), Linux kernel), e.g.:
+
+- 2 hours on a mid end 2012 laptop
+- 30 minutes on a high end 2017 desktop
+
+If you don't want to wait, you could also try to compile the examples and run them on your host as explained on the [run on host section](run-on-host.md), but as explained on that section, that is dangerous and will likely not work.
+
+After QEMU opens up, you can start playing with the kernel modules:
+
+    root
+    insmod /hello.ko
+    insmod /hello2.ko
+    rmmod hello
+    rmmod hello2
+
+This should print to the screen:
+
+    hello init
+    hello2 init
+    hello cleanup
+    hello2 cleanup
+
+which are `printk` messages from `init` and `cleanup` methods of those modules.
+
+See the [getting started section](getting-started.md) for further details.
