+| (Optional) `Stripe_Payment_Widget` | UI widget that calls this backend for creating payments |
+
+---
+
+### ⚙️ Installation Steps
+
+1. Import the Script Include XML:  
+   Navigate to **System Update Sets → Retrieved Update Sets → Import**  
+   and upload `sys_script_include_0a4e750983796e10cf0977447daad3a1.xml`.
+
+2. Create or update a **System Property**:
+
+   - Name: `stripe_payment_key`
+   - Value: your Stripe **secret key** (`sk_live_...` or `sk_test_...`)
+
+3. (Optional) Install the **Stripe Payment Widget** from your companion repo or PR.
+
+4. Link the widget to this processor by calling:
+   ```js
+   var processor = new global.StripePaymentProcessor();
+   var result = processor.createPaymentIntent({
+     payment_method_id: "pm_123",
+     amount: 2500,
+     currency: "usd",
+     metadata: { description: "Test Payment" },
+   });
+   ```
+
+### 🔗 Integration Path
+
+For a working demo, navigate to:
+Service Portal Page: /sp?id=stripe_payment_checkout
+→ This page contains the Stripe Payment Widget
+→ On submit, it triggers the StripePaymentProcessor backend call.
+
+🧠 Example Usage (Client → Server)
+
+In your widget’s Server Script:
+
+```
+(function() {
+    var processor = new global.StripePaymentProcessor();
+    data.result = processor.createPaymentIntent(input);
+})();
+
+```
+
+In Client Script (Angular Controller):
+
+```
+c.server.get({ payment_method_id: pm.id, amount: 1999 })
+  .then(function(response) {
+    console.log('Payment Intent:', response.data.result);
+  });
+
+```
