 ## Installation
 
-Modfy `native-app/index.js` to have the proper paths and filenames.
-
-Copy (or link) `native-app/interactive_bgm.json` into `~/.mozilla/native-messaging-hosts/`. Open `about:debugging`, click "Load Temporary Add-on...", and pick `extension/manifest.json`.
+Edit `native-app/interactive_bgm.json` to contain the full path of this directory on your system. Then copy (or link) that file into `~/.mozilla/native-messaging-hosts/`. Open `about:debugging`, click "Load Temporary Add-on...", and pick `extension/manifest.json`. Music should automatically start playing after a few seconds.
 
 (The music files included here, while WIP, are ripped from Hollow Knight.)
