 - `deploy` ships the project to the configured AWS account using the Serverless Framework CLI command.
 - `start` runs the `serverless-offline` provided server for local development and testing. Be sure to have the local docker infrastructure running to emulate the related services.
 - `test` runs `jest` under the hood.
-- `lint` runs `eslint` under the hood. You can use all the eslint available command line arguments. To lint the entire project, run `npm run lint .`, or equivalent. You can affix `--fix` to auto-correct linting issues that eslint can handle.

 ## Deployment
 
+<!-- TODO: add note about AWS setup -->
+
 As a serverless implementation, most of the infrastructure will be deployed and configured correctly simply utilizing the `deploy` script provided by this kit which is just an alias for [`serverless deploy`](https://www.serverless.com/framework/docs/providers/aws/cli-reference/deploy). However, the Redis instance is not configurable via the Serverless Configuration and will need to be set up ahead of your first deploy and configured via environment variables. We recommend using [Serverless Framework's interface for AWS Secret Manager](https://www.serverless.com/blog/aws-secrets-management/) for security purposes.
 
 This entire stack can be deployed via CI tools such as GitHub Actions, CircleCI, etc. and is our recommended approach as this kit is incompatible with the Serverless Dashboard. The Serverless Dashboard CI only works with the configuration in the YAML format which we do not use to give developers type-safety in the config file.
