 This allows to run the tests in a regular development machine with convenient debugging
 and fast turnaround. The only prerequisite is root permissions.
 
-The most convenient way to run the tests is doing the following as root:
-
-```
-$ unshare --ipc --mount --mount-proc --net --pid --fork /bin/bash
-  # then, in the newly opened shell session, perform the following
-$ mkdir -p empty
-$ mount --bind empty /dev
-$ mount --bind empty /sys
-  # now the tests can be run
-```

+The most convenient way to run the tests is running `./start-unshare.sh` as root.
 This creates a bare-bones environment that shares the filesystem with the rest of the system,
 but is otherwise isolated from it. This allows running additional X servers without affecting the
 primary X server running on the machine.
