+# Notifications
+
+Since [Android 8.0 Oreo, Google doesn't allow apps to run in the background anymore](https://developer.android.com/about/versions/oreo/background#services), requiring all apps which were previously keeping background connection to exclusively use its Firebase push messaging service. 
+
+As one can't use Google's push messaging in a FOSS app, Telegram-FOSS has to show you a notification to keep the background service running. Otherwise, you wouldn't be notified about new messages.
+
+Sadly, if the app would set the notification to lower priority (to hide it a bit in the lower part of the notification screen), you would immediately get a system notification about Telegram "using battery", which is confusing and is the reason for this not being the default. Despite Google's misleading warnings, there is no difference in battery usage between v4.6 in "true background" and v4.9+ with notification.
+
+## Make it better
+
+You may still lower the priority of the notification channel or even hide it altogether manually (make a long tap on the notification). You will then receive the misleading system notification, which [may be disabled as well with another long tap](https://9to5google.com/2017/10/26/how-to-disable-android-oreo-using-battery-notification-android-basics/).

+# Telegram-FOSS
 
 [Telegram](https://telegram.org) is a messaging app with a focus on speed and security. It’s superfast, simple and free.
-This repo contains the official source code for [Telegram App for Android](https://play.google.com/store/apps/details?id=org.telegram.messenger).
 
-## Creating your Telegram Application
+This is an unofficial, FOSS-friendly fork of the original [Telegram App for Android](https://github.com/DrKLO/Telegram).
+
+This version of Telegram is available on FDroid:

+
+## Changes:
 
-We welcome all developers to use our API and source code to create applications on our platform.
-There are several things we require from **all developers** for the moment.
+*Replacement of non-FOSS, untrustworthy or suspicious binaries or source code:*
+- Do location sharing with OpenStreetMap(osmdroid) instead of Google Maps
+- Use Twemoji emoji set instead of Apple's emoji
+- Google Play Services GCM replaced with Telegram's push service
+- Has to show a notification on Oreo+, ask Google
+- **SECURITY:** BoringSSL prebuilts are replaced with recent upstream source code built at compile time
+- **SECURITY:** FFmpeg prebuilts are replaced with recent upstream source code built at compile time
+- **SECURITY:** libvpx prebuilts are replaced with recent upstream source code built at compile time
+- **SECURITY:** Bundled libWebP is updated
 
-1. [**Obtain your own api_id**](https://core.telegram.org/api/obtaining_api_id) for your application.
-2. Please **do not** use the name Telegram for your app — or make sure your users understand that it is unofficial.
-3. Kindly **do not** use our standard logo (white paper plane in a blue circle) as your app's logo.
-3. Please study our [**security guidelines**](https://core.telegram.org/mtproto/security_guidelines) and take good care of your users' data and privacy.
-4. Please remember to publish **your** code too in order to comply with the licences.
+*Removal of non-FOSS, untrustworthy or suspicious binaries or source code and their functionality:*
+- Google Vision face detection and barcode scanning (Passport)
+- Google Wallet and Android Pay integration
+- Google Voice integration
+- HockeyApp crash reporting and self-updates
+- Google SMS retrieval. You have to type the code manually
+- Google ML Kit
 
-### API, Protocol documentation
+*Other:*
+- Added the ability to parse locations from intents containing a `geo:<lat>,<lon>,<zoom>` string
+- Force static map previews from Telegram
+- No content restrictions
+
+## Versioning
+
+This repository contains tags to make tracking versions easier.
+
+Versions are in form "v$UPSTREAM$RELEASE" where:
+
+* $UPSTREAM is the public, visible version of upstream.
+* $RELEASE is a letter ([a-z]) indicating minor releases between official versions (sometimes, upstream is updated without relating the changes to an specific version).

-### Compilation Guide
+## Building
+
+**NOTE: Building on Windows is, unfortunately, not supported.
+Consider using a Linux VM or dual booting.**
+![WindowsSupport](/tgfoss-build-under-win.gif?raw=true)
+
+**Important:**
+
+1. You need the Android NDK, Go(Golang) and [Ninja](https://ninja-build.org/) to build the apk.
+
+2. Don't forget to include the submodules when you clone:
+      - `git clone --recursive https://github.com/Telegram-FOSS-Team/Telegram-FOSS.git`
+
+3. Build native FFmpeg and BoringSSL dependencies:
+      - Go to the `TMessagesProj/jni` folder and execute the following (define the paths to your NDK and Ninja):
+
+      ```
+      export NDK=[PATH_TO_NDK]
+      export NINJA_PATH=[PATH_TO_NINJA]
+      ./build_libvpx_clang.sh
+      ./build_ffmpeg_clang.sh
+      ./patch_ffmpeg.sh
+      ./patch_boringssl.sh
+      ./build_boringssl.sh
+      ```
 
-**Note**: In order to support [reproducible builds](https://core.telegram.org/reproducible-builds), this repo contains dummy release.keystore,  google-services.json and filled variables inside BuildVars.java. Before publishing your own APKs please make sure to replace all these files with your own.
+4. If you want to publish a modified version of Telegram:
+      - You should get **your own API key** here: https://core.telegram.org/api/obtaining_api_id and create a file called `API_KEYS` in the source root directory.
+        The contents should look like this:
+        ```
+        APP_ID = 12345
+        APP_HASH = aaaaaaaabbbbbbccccccfffffff001122
+        ```
+      - Do not use the name Telegram and the standard logo (white paper plane in a blue circle) for your app — or make sure your users understand that it is unofficial
+      - Take good care of your users' data and privacy
+      - **Please remember to publish your code too in order to comply with the licenses**
 
-You will require Android Studio 3.4, Android NDK rev. 20 and Android SDK 8.1
+The project can be built with Android Studio or from the command line with gradle:
 
-1. Download the Telegram source code from https://github.com/DrKLO/Telegram ( git clone https://github.com/DrKLO/Telegram.git )
-2. Copy your release.keystore into TMessagesProj/config
-3. Fill out RELEASE_KEY_PASSWORD, RELEASE_KEY_ALIAS, RELEASE_STORE_PASSWORD in gradle.properties to access your  release.keystore
-4.  Go to https://console.firebase.google.com/, create two android apps with application IDs org.telegram.messenger and org.telegram.messenger.beta, turn on firebase messaging and download google-services.json, which should be copied to the same folder as TMessagesProj.
-5. Open the project in the Studio (note that it should be opened, NOT imported).
-6. Fill out values in TMessagesProj/src/main/java/org/telegram/messenger/BuildVars.java – there’s a link for each of the variables showing where and which data to obtain.
-7. You are ready to compile Telegram.
+`./gradlew assembleAfatRelease`
