-Running dwm
------------
+## Running dwm
 Add the following line to your .xinitrc to start dwm using startx:
-
+```bash
     exec dwm
+```
 
 In order to connect dwm to a specific display, make sure that
 the DISPLAY environment variable is set correctly, e.g.:
 
+```bash
     DISPLAY=foo.bar:1 exec dwm
-
-(This will start dwm on display :1 of the host foo.bar.)
-
+```
 In order to display status info in the bar, you can do something
 like this in your .xinitrc:
 
-    while xsetroot -name "`date` `uptime | sed 's/.*,//'`"
+```bash
+        while xsetroot -name "`date` `uptime | sed 's/.*,//'`"
     do
     	sleep 1
     done &
     exec dwm
+```

-Configuration
--------------
+## Configuration
 The configuration of dwm is done by creating a custom config.h
 and (re)compiling the source code.
