 Obviously, this library requires the Zenity binary itself.
 Zenity already ships with Ubuntu-based distributions and should not require any installation there.
 On Debian- and Ubuntu-based distributions you can make sure it's installed like this:
 
 ```bash
 # usually not required
-$ sudo apt-get install zenity
+sudo apt-get install zenity
 ```
 
 Otherwise you may have to install Zenity yourself (use your favorite search engine, download the appropriate release tarball or compile from source).
