-This C# library provides functionality for interacting with the Immutable X Marketplace, including on-ramp services.
+---
 
-## Version Support
+# Immutable Unity SDK - Marketplace  
 
-This library supports:
+The Immutable SDK Marketplace package for Unity simplifies integrating marketplace functionality, such as adding funds to a player's wallet.  
 
-- Unity 2020.3 (LTS) and up
-- .NET Standard 2.1 / .NET Framework
+## Documentation  
 
-## Dependencies
-
-- [UniTask](https://github.com/Cysharp/UniTask) - For asynchronous operations
-- Unity Engine
-
-## Installation
-
-Add the dependencies to your Unity project. You can do this through the Package Manager or by adding them to your `Packages/manifest.json`:
-
-```json
-{
-  "dependencies": {
-    "com.cysharp.unitask": "https://github.com/Cysharp/UniTask.git?path=src/UniTask/Assets/Plugins/UniTask",
-    "com.unity.nuget.newtonsoft-json": "3.0.2"
-  }
-}
-```
-
-## Usage
-
-Here's an example of how to use the OnRamp functionality with Immutable Passport:
-
-```csharp
-using Immutable.Marketplace.OnRamp;
-using Immutable.Passport;
-using Immutable.Passport.Model;
-using System.Collections.Generic;
-using UnityEngine;
-
-public class MarketplaceExample : MonoBehaviour
-{
-    async void Start()
-    {
-        string environment = Environment.SANDBOX;
-        string email = await Passport.Instance.GetEmail();
-        List<string> walletAddresses = await Passport.Instance.ZkEvmRequestAccounts();
-
-        OnRamp onRamp = new OnRamp(environment, email, walletAddresses.FirstOrDefault());
-
-        try
-        {
-            string link = await onRamp.GetLink();
-            Debug.Log($"onRamp.GetOnRampLink: {link}");
-
-            // Open the generated link in the default browser
-            Application.OpenURL(link);
-        }
-        catch (System.Exception e)
-        {
-            Debug.LogError($"Error getting on-ramp link: {e.Message}");
-        }
-    }
-}
