# Getting started

- [Build Your First Android App](https://docs.mitter.io/getting-started/build-your-first-android-app.md): Get started with Mitter.io by building a fully functional app that sends/receives messages in a group of users.
- [Setup](https://docs.mitter.io/getting-started/build-your-first-android-app/setting-up.md): We’ll get started by setting up the SDK first.
- [Authenticate a User](https://docs.mitter.io/getting-started/build-your-first-android-app/authenticate-a-user.md): Add some users to your app and authenticate via the SDK.
- [Start a Basic Chat](https://docs.mitter.io/getting-started/build-your-first-android-app/start-a-basic-chat.md): Let’s take this tutorial even further by building a simple chat UI and using Mitter.io to send/receive messages.
- [Selective Deliveries](https://docs.mitter.io/getting-started/build-your-first-android-app/selective-deliveries.md): Mitter provides Access Control Lists (ACLs) out of the box to let you choose whom to deliver a message to in a group channel. Let’s add a little function to our app to see this in action.
- [Custom Payloads](https://docs.mitter.io/getting-started/build-your-first-android-app/custom-payloads.md): Learn how to add actions & extra information to your messages and build a playful and engaging chat experience.
