+# API Gateway
+
+Creating an API Gateway with its various endpoints, methods, and access policies by hand
+is tedious and labor-intensive. Developers are helped significantly by using tools such as
+SAM (Sserverless Application Model), AWS Cloud Development Kit (CDK), Hashicorp Terraform,
+or Chalice.
+
+Chalice is a python-based package that supports the creation of API Gateway endpoints, resources,
+methods, and access policies, as well as the Lambda functions behind them.
+
+The demo in this directory offers a simple example of a Chalice-derived API. Once you have installed
+Chalice and other dependencies, this command will run the API locally:
+
+```
+chalice local
+```
+
+To deploy a working API:
+
+```
+chalice deploy
+```
