+## Aspose.PDF for AWS Trial
+
+You can start using **Aspose.PDF for AWS** right away in **trial mode**. 
+Just works when you launch configured the container. 
+
+### What to expect in trial mode:
+- Some advanced APIs and formats have evaluation watermark
+- Document size is [limited](https://docs.aspose.com/pdf/net/licensing/#limitation-of-an-evaluation-version) (about **4 pages, 4 elements per page**).
+- The container runs for **one hour at a time**. Want more time? Just restart the container.
+
+Trial mode is perfect for exploring features and checking if the product fits your needs.  
+
+### Why Enable Billing?  
+
+- No evaluation watermark
+- Process **unlimited pages**  
+- Access **advanced APIs and features**  
+- Unlock **all supported formats**  
+- Run containers continuously without trial limits  
+
+### If You See an Error on trial 
+
+Without the right permission, you may see an error like this:  
+
+```bash
+arn:aws:sts::111111111:assumed-role/ecsInstanceRole/i-22222222 is not authorized to perform: aws-marketplace:MeterUsage
+```
+
+This simply means the IAM role of container doesn’t have the **MeterUsage** action to bill. Add the policy above, restart, and you’re good to go to full version.  
+
+## Billing
+
+When you’re ready to move beyond trial, enable **metered billing**. This unlocks full document processing and all supported APIs.  
+
+By default, AWS roles don’t allow billing. You’ll need to give your container permission to call the AWS **MeterUsage API**.  
+
+### How to enable billing:
+
+1. Open the [IAM Console](https://console.aws.amazon.com/iam/).  
+2. Find the IAM role used by your ECS/EKS instance (often called `ecsInstanceRole`).  
+3. Add this policy to the role (new policy or inline):  
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": "aws-marketplace:MeterUsage",
+      "Resource": "*"
+    }
+  ]
+}
+```  
+
+4. Save the role and restart your container.  
+5. Done — billing is active and your container is no longer limited to trial mode.
