+
+# Build Instructions
+
+## General
+
+- **Build Settings:** Use `Smaller (faster) Builds` / `Shorter Build Time`.
+- **Player Settings:** Use IL2CPP over Mono when available.
+- **Stripping Level:** Set `Managed Stripping Level` to `Minimal` (`Player Settings` > `Other Settings` > `Optimization`). (Generally not a hard requirement unless using WalletConnect as a wallet provider option.)
+
+## WebGL
+
+- **WebGL Template:** None enforced, feel free to customize!
+- **Compression Format:** Set to `Disabled` (`Player Settings` > `Publishing Settings`) for final builds.
+- **Testing WebGL Social Login Locally:** Host the build or run it locally with `Cross-Origin-Opener-Policy` set to `same-origin-allow-popups`.
+
+Example setup for testing In-App or Ecosystem Wallet Social Login locally:
+
+```javascript
+// YourWebGLOutputFolder/server.js
+const express = require("express");
+const app = express();
+const port = 8000;
+
+app.use((req, res, next) => {

+	next();
+});
+
+app.use(express.static("."));
+app.listen(port, () =>
+	console.log(`Server running on http://localhost:${port}`),
+);
+
+// run it with `node server.js`
+```
+
+No action needed for hosted builds.
+
+## Mobile
+
+- **EDM4U:** Comes with the package, resolves dependencies at runtime. Use `Force Resolve` from `Assets` > `External Dependency Manager` > `Android Resolver`.
+- **Redirect Schemes:** Set custom schemes matching your bundle ID in `Plugins/AndroidManifest.xml` or equivalent to ensure OAuth redirects.

+If you are wrapping the SDK, we recommend making your own Manager inspired by `ThirdwebManager.cs`, specifically for `ThirdwebClient` initialization.
 
 ## Configuration
 
 Configure `ThirdwebManager` through the Unity Inspector window.

+
+This section involves the required thirdweb client settings to configure the SDK:
 
 - `Client ID`: Thirdweb [API Key](https://thirdweb.com/create-api-key). Used to access thirdweb services such as RPC, Storage, and Account Abstraction.
 - `Bundle ID`: The bundle ID used to access thirdweb services from native platforms. Should be the same as the bundle ID in your Unity project, e.g., `com.companyname.gamename`.
+- `Create API Key`: A link to create a new API key if you don't have one.
+
+### Preferences

+<DocImage src={thirdwebmanager_preferences} />
+
+This section allows you to define the default preferences for the SDK:
+
 - `Initialize On Awake`: Whether the SDK should initialize on awake or not. If not, you can call `ThirdwebManager.Instance.Initialize()` to initialize it manually.
 - `Show Debug Logs`: Whether to show thirdweb SDK debug logs.
 - `Opt Out Usage Analytics`: Whether to opt out of Connect usage analytics, such as the number of wallets connected to your game.

+- `Log Active Wallet Info`: Logs the active (last connected) wallet's information such as its address.
+- `Open Documentation`: Opens the thirdweb SDK documentation in your default browser.
 
 ## Interacting with the ThirdwebManager
 
 Once your `ThirdwebManager` is set up, you can interact with it using the following methods:
 
-### Initialize

 ```csharp
