+# Yoga Graphql response streaming example
+
+This example show how to use Lambda Web Adapter to run a yoga server application with response streaming via a [AWS Lambda](https://aws.amazon.com/lambda) Function URL.
+
+### Build and Deploy
+
+Run the following commands to build and deploy the application to lambda. 
+```
+
+```bash
+sam build
+
+sam deploy --guided
+```
+When the deployment completes, the Function URL will appear in the output list, which is the entrypoint for accessing
+
+### Verify it works
+
+When you open the Function URL in a browser:
+
+1. Write and execute GraphQL queries in the left panel
+2. See the results in the right panel
+3. Explore the API documentation using the "Docs" button
+
+Try this sample subscription query to test streaming:
+
+```graphql
+subscription {
+  stream(addition: "testing")
+}
+```
+
+You'll see each character stream in one by one with a small delay between them.
+
+For command line testing, you can use curl:
+
+```bash
+curl --no-buffer -N \
+  -H "Content-Type: application/json" \
+  -H "Accept: text/event-stream" \
+  -d '{"query": "subscription { stream(addition: \"test\") }"}' \
+  https://your-function-url.lambda-url.us-east-1.on.aws/graphql
+```
+
