 # Bedrock Access Gateway
 
 OpenAI-compatible RESTful APIs for Amazon Bedrock
 
 ## What's New 🔥
 
-This project supports reasoning for both **Claude 3.7 Sonnet** and **DeepSeek R1**, check [How to Use](./docs/Usage.md#reasoning) for more details. You need to first run the Models API to refresh the model list.
+This project now supports **Claude Sonnet 4.5**, Anthropic's most intelligent model with enhanced coding capabilities and complex agent support, available via global cross-region inference.

 **Step 1: Create your own API key in Secrets Manager (MUST)**
 
-
 > **Note:** This step is to use any string (without spaces) you like to create a custom API Key (credential) that will be used to access the proxy API later. This key does not have to match your actual OpenAI key, and you don't need to have an OpenAI API key. please keep the key safe and private.
 
 1. Open the AWS Management Console and navigate to the AWS Secrets Manager service.

 3. In the "Choose secret type" page, select:
 
    Secret type: Other type of secret
    Key/value pairs:
    - Key: api_key
    - Value: Enter your API key value

+
+3. Follow the prompts to configure:
+   - ECR repository names (or use defaults)
+   - Image tag (or use default: `latest`)
+   - AWS region (or use default: `us-east-1`)

 ### How to upgrade?
 
-To use the latest features, you don't need to redeploy the CloudFormation stack. You simply need to pull the latest image.
-
-To do so, depends on which version you deployed:
-
-- **Lambda version**: Go to AWS Lambda console, find the Lambda function, then find and click the `Deploy new image` button and click save.
-- **Fargate version**: Go to ECS console, click the ECS cluster, go the `Tasks` tab, select the only task that is running and simply click `Stop selected` menu. A new task with latest image will start automatically.

+To use the latest features, you need follow the deployment guide to redeploy the application. You can upgrade the existing CloudFormation stack to get the latest changes.
