-### Add `qemush` in the `PATH`
+### Via `Makefile` (recommended)
 
-Use your preferred way to add the `qemush` script to a folder of `PATH`.
-Recommended: copy the script in `/usr/local/bin` to make it effortlessly
-system wide.

-### Add `qemush` modules in `~qemu/bin`

-`qemush` needs reusable script modules like `diskpath` in its custom `bin`
-folder located at `~qemu/bin`. You can add them directly via `qemush` from
-this repo via the following command :
+Just run the following command at the root of this repository to install
+`qemush` (previous step is **mandatory**) :
 
 ```sh

-`first-free-port` is a small C program designed accordingly to the Unix
-philosophy to show in `stdout` the first free (not listening) TCP port
-after `argv[1]`, or `argv[1]` if it is free. You will need it to allocate
-ports to protocols like SPICE in your launching scripts (example in
-`qemu/bin/*-spice`).
+You'd be right. The next section is the exhaustive list of steps handled
+by the `Makefile` for the installation process.
 
-Example `qemush` command to add the program to a local `qemu` `bin` folder

+### Manual installation (what does the `Makefile` do)
 
-```sh
