 If `gitea` can use three different types of database, the documentation should simply pick one and continue instructions from there.

 ## Three Input Types
 
 There are three types of examples:
 
 Fixed input:
 
-> ls
-
-Arbitrary Input shows the non-fixed input in italics:
-
-> ls *myFile.txt*
-
-Output shows as unformatted text:
-
+```bash
+ls
 ```
-    LK           img
-    Mail         kn
-    Projects     music
+
+Anything with arbitrary input should be shown as a variable.
+
+```bash
+ls $FILE
 ```
 
+Non-commands (e.g. output) should be shown as quoted text:
+
+> LK           img
+> Mail         kn
+> Projects     music
