-### Usage
+### Compilation Guide
 
-**Beware of using the dev branch and uploading it to any markets, in many cases it not will work as expected**.
+You will require Android Studio 3.4, Android NDK rev. 16b (https://developer.android.com/ndk/downloads/older_releases.html) and Android SDK 8.1
 
-First of all, take a look at **src/main/java/org/telegram/messenger/BuildVars.java** and fill it with correct values.
-Import the root folder into your IDE (tested on Android Studio), then run project.
+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.
