Using my own patched version of dmenu

Instead of installing the default package I clone and install my own
version that already has some additional patches.

 ## Installation
 
-+ Clone or [download] this repository.
-+ `cd` into its directory.
-+ Launch the `install.sh` script like so:
-    ```shell
-    ./install.sh
-    ```
+**Note:** It only works on <u>Ubuntu</u> or <u>Arch</u> based distributions, since it uses either `apt` or `pacman` to install.
+
+```shell
+git clone https://github.com/marcoplaitano/evemenu
+cd evemenu && ./install.sh
+```
+
+What the `install.sh` script does is installing [my own patched version] of
+dmenu with all its dependencies.
+
+**Note:** `evemenu` will be in `$HOME/.local/bin`; make sure this is in
+`$PATH`.
