 A shy Gopher client made with Flutter for Android (and maybe desktop)
 
-Not even in Alpha state, it can browse text files over Gopher but it's not usable yet
+In Alpha state, you can use it if you're tough, for more see Current Usability
 
 Eventually will be on F-Droid
+
+## Current usability status: kinda usable
+
+You can navigate GoperDirectories, read plaintext files and go back in navigation stack.  
+App starts when you click on ``gopher://`` link.

+List of [features and TODOs](/features.org)

+[Link to test gopher page](gopher://treebrary.org/Directory/) because it's hard to find gopher link on the web these days for some
+reason.
