To get started, run yarn in both the microfrontend as well as the shell folder.
The microfrontend folder contains a standalone microfrontend that exposes its <App> component. To start this microfrontend, run yarn start.
The shell folder contains a shell application that has a pointer to the remote microfrontend. It fetches the microfrontend's <App> at run-time and mounts it. To start it, run yarn start.
