+# Get Started
+
+## 1. Install `mongodb-realm-cli`
+
+You can import the ready-made MongoDB Realm backend using the
+`mongodb-realm-cli`, which you can install with npm:
+
+```bash
+npm install -g mongodb-realm-cli
+```
+
+## 2. Create an Atlas cluster with MongoDB 4.4+
+
+To have a backend for your Task Tracker app, you will need a MongoDB Atlas
+cluster with MongoDB 4.4 or higher. To create an Atlas account, project, and cluster, visit the [Atlas
+UI](https://cloud.mongodb.com/?tck=docs_realm).
+
+> ⚠️ Sync requires MongoDB 4.4 or above. Be sure to select at least MongoDB
+> version 4.4 when building your cluster!
+
+## 3. Create an API Key and authenticate the CLI
+
+To authenticate with the `realm-cli`, you must create an API key with **Project
+Owner** permissions for your project in the **Project Access Manager** view.
+Click the **Access Manager** at the top of the Atlas view to find it. Please
+follow the [instructions on the MongoDB documentation
+site](https://docs.mongodb.com/realm/deploy/realm-cli-reference/#authenticate-a-cli-user)
+for more information.
+
+Once created, pass the API keys to `realm-cli login` to log in:
+
+```bash
+realm-cli login --api-key=[public API key] --private-api-key=[private API key]
+```
+
+## 4. Import the Realm backend app
+
+If logged in successfully, you can now import the app:
+
+```bash
+realm-cli import --app-name tasktracker --path ./backend/
+```
+
+Follow the prompts and wait for the app to deploy.
+
+Congratulations! You now have a working MongoDB Realm backend with Sync enabled.
