 On first run and when invoked with `firestarter -g`, Firestarter will generate a series of configuration files in `~/.config/firestarter`. These files consist of several lines that look somewhat like the following:
 
-    command -v i3
-    i3
+```bash
+command -v i3
+i3

 Every odd line is a command that must succeed in order for the following even line to be executed. Once an even command is executed, parsing stops. When Firestarter is invoked with no arguments, every configuration file is parsed this way.

 By setting a dummy execution line, one can effectively prevent an entire configuration file from being parsed in certain environments. As an example, the following configuration file will only attempt to start an X infobar in an X environment:
 
-    [ -z "$DISPLAY" ]
-    :
-    command -v polybar
-    polybar bar
-    command -v lemonbar
-    ~/.bin/lemonbar.sh | lemonbar
+```bash
+[ -z "$DISPLAY" ]
+:
+command -v polybar
+polybar bar
+command -v lemonbar
+~/.bin/lemonbar.sh | lemonbar
+```
 
 After all these programs have been started, firestarter executes `~/.firestarterrc` if it exists.
