 ## Getting Started
-You will need node>=20 installed, as well as the AWS CLI and the AWS SAM CLI. The best way to work with all of this is to open the environment in a container within your IDE (VS Code should prompt you to do so: use "Clone in Container" for best performance). This container will have all needed software installed.

 Then, run `make install` to install all packages, and `make local` to start the UI and API servers! The UI will be accessible on `http://localhost:5173/` and the API on `http://localhost:8080/`.
