 This sample shows how to deploy asynchronous functions to [Cloud Run functions](https://cloud.google.com/functions) with the Functions Framework. It includes examples for both HTTP and CloudEvent functions, which can be found in the `main.py` file.
 
 ## Dependencies
+
 Install the dependencies for this example:
+
 ```sh
 pip install -r requirements.txt
 ```
 
 ## Running locally
 
 ### HTTP Function
+
 To run the HTTP function locally, use the `functions-framework` command:
+
 ```sh
 functions-framework --target=hello_async_http
 ```
+
 Then, send a request to it from another terminal:
+
 ```sh
 curl localhost:8080
 # Output: Hello, async world!
 ```
 
 ### CloudEvent Function
+
 To run the CloudEvent function, specify the target and set the signature type:
+
 ```sh
 functions-framework --target=hello_async_cloudevent --signature-type=cloudevent
 ```
+
 Then, in another terminal, send a sample CloudEvent using the provided script:
+
 ```sh
 python send_cloud_event.py
 ```
 
 ## Deploying to Cloud Run
+
 You can deploy these functions to Cloud Run using the `gcloud` CLI.
 
 ### HTTP Function
+
 ```sh
 gcloud run deploy async-http-function \
     --source . \

 ### CloudEvent Function

 gcloud run deploy async-cloudevent-function \

-    --set-env-vars=FUNCTION_SIGNATURE_TYPE=cloudevent
+    --region <YOUR_REGION>
 ```
+
 After deploying, you can invoke the CloudEvent function by sending an HTTP POST request with a CloudEvent payload to its URL.
