 ## Basic commands
 
 List available patches:
 
-    python troi list
+    troi list
 
 Generate a playlist using a patch:
 
-    python troi playlist --print [patch-name]
+    troi playlist --print [patch-name]
 
 If the patch requires arguments, running it with no arguments will print a usage statement, e.g.
 
-    $ python troi playlist --print area-random-recordings
+    $ troi playlist --print area-random-recordings
     Usage: area-random-recordings [OPTIONS] AREA START_YEAR END_YEAR
 
       Generate a list of random recordings from a given area.
