+> This is a simple Agora token gen backend to be used with a front-end to use Agora services
+
+- Create an audio and video app using agora quick start guide
+- Add in call stats
+- add group chat
+- discuss how it works in detail
+- demonstrate how it runs.
+
+
+## Useful commands
+
+ * `npm run build`   compile typescript to js
+ * `npm run watch`   watch for changes and compile
+ * `npm run test`    perform the jest unit tests
+ * `cdk deploy`      deploy this stack to your default AWS account/region
+ * `cdk diff`        compare deployed stack with current state
+ * `cdk synth`       emits the synthesized CloudFormation template
+
+ * `cdk --version`   To get the current version of the CDK
+ * `aws sts get-caller-identity --profile fff` to get the account number of the currently selected profile
+
+## To deploy:
+- `cd CDK/lambda` and then run `npm i` there
+- Run `cdk bootstrap --profile fff` // only run once, for the first time.
+- Run `cdk diff --profile fff` // to see the recent changes before deploying them.
+- Run `cdk deploy --profile fff`
+- Run `cdk deploy --hotswap --profile fff` For a fast re-deploy ( DON'T USE IN PRODUCTION! )
+- Run `npm run watch` for continous hot-swap ( if needed edit `package.json` to include / exclude files in the watch )
