 # Bookwyrm-android
 An Android application for Bookwyrm. Basically, it is just bookwyrm put into a 'webview' element.
 What it does? It enables you to use BookWyrm on your Android phone without having to use a browser to go to it every time.
-It can also open links to userpages of Bookwyrm users.
+It can also open links to userpages of Bookwyrm users and it can scan ISBN codes.
 
 This application works on: Android 6 and above.
 
 And if you want to know, I am `@StoryDragon@wyrms.de` on BookWyrm.
+
+For the ISBN-scanning I use the library zxing-android-embedded.
+The barcode icon that is added for instances that do not have ISBN-scanning by default comes from the Remix Icon project.
