 # Bookwyrm-android
-A crappy attempt at creating an Android application for Bookwyrm. Basically, it is just bookwyrm put into a 'webview' element. Also, I am not sure whether the credentials are stored in a safe way, so be warned! (If you know how to make it safer, please do a pull request!)
+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 and it can scan ISBN codes.
 
+This application works on: Android 6 and above.
+
+And if you want to know, I am [`@StoryDragon@books.storydragon.nl`](https://books.storydragon.nl/user/storydragon) 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.

+This is an Android client for BookWyrm – a federated social network for tracking your reading, talking about books, writing reviews, and discovering what to read next. It is just BookWyrm put into a webview element, nothing special – but it adds some convenience on top:
+
+* bookwyrm links can be made to open with the app (e.g. clicking on the link to someone's userprofile will open that from your own bookwyrm instance)
+* thanks to that, you can immediately follow them easily if you want.
+* it lets you easily return to your own home timeline when viewing something like posts, on another bookwyrm instance, because the 'back' button is then modified for that.
+* You can also search for books by scanning the ISBN, no matter what instance of Bookwyrm you use.
+
+<b>This application is <u>not</u> an official client!</b> (An official client does not exist yet, as far as I know)
+
+The ISBN scanning feature is created with the zxing-android-embedded library.
