 On Debian/Ubuntu-like Linux, you can install mbrola using `apt-get` package manager:
 
 	sudo apt-get install mbrola mbrola-en1
 
 where:
 
-* `mbrola` is package containing Mbrola executable,
-* `mbrola-en1` is mbrola data files for **en1** Mbrola voice.
+* `mbrola` is package containing MBROLA executable,

 These steps are described in details in following sections.
