 # Installation
 
+You can start using Talawa by any of the two methods:
+
+1. Install the `apk` provided in the release section of this repo. It is built against the latest codebase. Please note that the release is provided only for Android. For iOS, you will still need to build the app yourself.	
+   - Head over to the [release section](https://github.com/PalisadoesFoundation/talawa/releases) of Talawa repository.
+   - You will find a release with the name of `Automated Android Release`. Scroll a bit and you will find a file named `app-release.apk`. Click on it and have it downloaded.
+   - Head over to the downloads of your browser and then click on `app-release.apk` there. That will ask you to install the app. Click on `Install`.
+   - Once done, you can find `Talawa` in your apps list. Start using it from right there :)
+2. Manually build the app by below described steps.
