-# Android GUI for [WireGuard](https://www.wireguard.com/)
+# Wire VPN for Android
 
-**[Download from the Play Store](https://play.google.com/store/apps/details?id=com.wireguard.android)**
+**A fork of [WireGuard for Android](https://git.zx2c4.com/wireguard-android/about/), rebranded as Wire VPN.**
 
-This is an Android GUI for [WireGuard](https://www.wireguard.com/). It [opportunistically uses the kernel implementation](https://git.zx2c4.com/android_kernel_wireguard/about/), and falls back to using the non-root [userspace implementation](https://git.zx2c4.com/wireguard-go/about/).
+Package: `page.onram.wirevpn` · Available from our [F-Droid repository](https://git.obahan.xyz/frank/wirevpn) on release.

+Wire VPN is an Android GUI for [WireGuard](https://www.wireguard.com/). It [opportunistically uses the kernel implementation](https://git.zx2c4.com/android_kernel_wireguard/about/), and falls back to using the non-root [userspace implementation](https://git.zx2c4.com/wireguard-go/about/).
+
+## What changed from upstream
+
+- App name rebranded from *WireGuard* to *Wire VPN*
+- New launcher icon (padlock with a bold W in a circle)
+- Application ID changed to `page.onram.wirevpn` (Java/Kotlin package is `page.onram.wirevpn`)
+- GitHub Actions pipeline: every new Git release automatically builds a signed release APK and produces F-Droid v2 repository artifacts
+- Upstream in-app auto-updater and donation links removed (we distribute via our own F-Droid repo)
 
 ## Building
 
 ```
-$ git clone --recurse-submodules https://git.zx2c4.com/wireguard-android
-$ cd wireguard-android
+$ git clone --recurse-submodules https://git.obahan.xyz/frank/wirevpn.git
+$ cd wirevpn
 $ ./gradlew assembleRelease
 ```
 
-macOS users may need [flock(1)](https://github.com/discoteq/flock).
+The build compiles the tunnel backend natively (CMake + NDK) and the userspace
+WireGuard implementation in Go (Go 1.24.3 is fetched and hash-checked by the
+build automatically).
 
-## Embedding
-
-The tunnel library is [on Maven Central](https://search.maven.org/artifact/com.wireguard.android/tunnel), alongside [extensive class library documentation](https://javadoc.io/doc/com.wireguard.android/tunnel).
+To sign with a keystore, export:
 
 ```
-implementation 'com.wireguard.android:tunnel:$wireguardTunnelVersion'
+export KEYSTORE_FILE=/path/to/keystore.jks
+export KEYSTORE_PASSWORD=...
+export KEY_ALIAS=...
+export KEY_PASSWORD=...
 ```
 
-The library makes use of Java 8 features, so be sure to support those in your gradle configuration with [desugaring](https://developer.android.com/studio/write/java8-support#library-desugaring):
-
-```
-compileOptions {
-    sourceCompatibility JavaVersion.VERSION_17
-    targetCompatibility JavaVersion.VERSION_17
-    coreLibraryDesugaringEnabled = true
-}
-dependencies {
-    coreLibraryDesugaring "com.android.tools:desugar_jdk_libs:2.0.3"
-}
-```
+Releases are cut by creating a Git tag/release on `main` (e.g. `v1.0.x`); the
+`release.yml` GitHub Action builds and publishes the artifacts.
 
 ## Translating
