 ## Requirements
 LilyPond version 2.24.1 or higher.  It is assumed that `lilypond` is in the PATH of your system.
 
 ## Producing PDFs or other outputs
 You can find the latest release of the PDF and MIDI files [here](https://github.com/ksnortum/chopin-opus-62/releases/latest), otherwise `cd` into your installation directory and type:
 
-        lilypond twelve-etudes-opus62-book.ly
+        lilypond two-nocturnes-op62-book.ly
 
 This should produce a PDF and two MIDI files.
