-## ⚡️ Installation
-
-Use your favorite package manager to install `@stacks/connect` in your project.
-Follow the **Getting Started** section of the [`@stacks/connect` README](https://github.com/hirosystems/connect/tree/main/packages/connect).
-
-> Or use one of our starter-templates to bootstrap a fresh project already including connect using the [command-line](https://github.com/hirosystems/stacks.js-starters) locally via `npm create stacks`
+## Development Notes
 
-## 📦 Packages
+### Packages
 
 This repository includes three packages:
 
 - [`@stacks/connect`](./packages/connect): The one-stop-shop tool for letting web-apps interact with Stacks web wallets.
 - [`@stacks/connect-ui`](./packages/connect-ui): A web-component UI for displaying an intro modal in Stacks web-apps during authentication _(used in the background by `@stacks/connect`)_.
 - ~~[`@stacks/connect-react`](./packages/connect-react): A wrapper library for making `@stacks/connect` use in React even easier~~

 The latest spec uses a simple JS Object exposing a `.request(method: string, params?: object)` method.

 Previously, the `UserSession` class was used to access the user's addresses and data, which abstracted away the underlying implementation details.
 Now, the `request` method is used to directly interact with the wallet, giving developers more explicit control and clarity over what's happening under the hood.
 This manual approach makes the wallet interaction more transparent and customizable.

+## Error Handling
+
+The `request` method returns a Promise, allowing you to handle errors using standard Promise-based error handling patterns. You can use either `try/catch` with `async/await` or the `.catch()` method with Promise chains.
+
+### Using try/catch with async/await
+
+```ts
+import { request } from '@stacks/connect';
+
+try {
+  const response = await request('stx_transferStx', {
+    amount: '1000',
+    recipient: 'SP2MF04VAGYHGAZWGTEDW5VYCPDWWSY08Z1QFNDSN',
+  });
+  // SUCCESS
+  console.log('Transaction successful:', response.txid);
+} catch (error) {
+  // ERROR
+  console.error('Wallet returned an error:', error);
+}
+```
+
+## Compatibility
+
+The `request` method by default adds a layer of auto-compatibility for different wallet providers.
+This is meant to unify the interface where wallet providers may not implement methods and results the same way.
