+## Overview

 When discography is correctly tagged - at least artist and title field - scrobbling needs no
 further configuration (see: [Configuration](#configuration)). However, if this requirement is not
 met, then one can use POSIX ERE-based file name parser feature. But what the heck is this?

-Configuration
--------------
+## Configuration
 
 Before usage with the cmus music player, one has to grant access for the cmusfm in the Last.fm
 service. To do so, simply run cmusfm with the `init` argument and follow the instruction. This
 action might be also required when upgrading to the newer version with new features.
 
-	$ cmusfm init
+```shell
+cmusfm init
+```
 
 After that you can safely edit `~/.config/cmus/cmusfm.conf` configuration file.
 
 ~~Note, that for some changes to take place, restart of the cmusfm server process is required. To

 As a final step (after the access is granted in the Last.fm service) one should set cmusfm as a
 status display program for cmus. This can be done by starting cmus and typing in the main window:
 
-	:set status_display_program=cmusfm
+```shell
+:set status_display_program=cmusfm

 Enjoy!
