     - functions as a intermediator between your installed app and the website to manage what files are installed locally on the client machine and grabs new files as updates are made
-- a manifest.json file 
+- a manifest file (`manifest.json`) 
     - provides a list of the files and icons needed by the service worker along with other app-related metadata
 
-All of the icon files were created with [favicon.ico](https://favicon.io/favicon-converter/)). 
+All of the icon files are in the `images` folder. These are used for either the home screen icon on Android and iOS or the desktop application icon. They were created with [favicon.ico](https://favicon.io/favicon-converter/).
