-## Using
+## Usage
 
 The main concept is that the composer will write a ReaScript script in Python 
 to algorithmically generate a score as a list of MIDI notes, either using 
-CsoundAC, or using plain Python. The script must call the `score_to_midiitem` 
-function to send the generated score to Reaper.
-
-The composer then selects a MidiItem in Reaper, and runs the script to  
-generate the score and send its notes to the MidiItem, which is resized to fit 
-the notes.
+CsoundAC, or using plain Python. The script must add the directory containing 
+`ac_python.py` to the Python `sys.path` list, and import `ac_python`. After 
+generating the score, the script must call the `score_to_midiitem` function to
+send the generated score to Reaper.
+
+To actually use the script, the composer selects a MidiItem on a Reaper Track, 
+and runs the script to generate the score and send its notes to the MidiItem, 
+which is resized to fit the notes.
 
 If a MidiItem is not selected, a new MidiItem is created on the first track.
