+### 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 :
+
+```sh
+qemush run 'mkdir -p ~/bin && cp -v qemu/bin/* "$_"'
+```
+
 ### Extra: add `first-free-port` in `PATH`
 
 `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 can compile it and add
-it to your `PATH` if you need to allocate ports to protocols like SPICE in
-your launching scripts (example in `qemu/bin/*-spice`). Its source is in
-`src` folder of this repository.
