## Prerequisites [#prerequisites]

To get started, you will need the following three requirements:

* Unity Game or Application
* Backend Web Server with an accessible API
* Bolt Merchant Dashboard

To read about how this all comes together with a Node.js web server, [you can check out this scenario we've put together.](/gaming/guide/unity/nodejs)

## Install the SDK [#install-the-sdk]

### Option #1 - Using the Unity manifest.json (Recommended) [#option-1---using-the-unity-manifestjson-recommended]

* Open your Unity project
* Navigate to the Packages folder in your project root
* Open the manifest.json file in a text editor
* Add the Bolt SDK dependency to the dependencies section:

```json title="manifest.json"
{
  "dependencies": {
    "com.bolt.sdk": "https://github.com/BoltApp/bolt-unity-sdk.git#main"
  }
}
```

* ***Save the file*** - Unity will automatically download and import the package

### Option 2: Using Package Manager UI [#option-2-using-package-manager-ui]

* Open Package Manager in Unity (Window > Package Manager)
* Click the "+" button in the top-left corner
* Select "Add package from git URL"
* Enter the repository URL: [https://github.com/BoltApp/bolt-unity-sdk.git](https://github.com/BoltApp/bolt-unity-sdk.git)
