This is the app shell package for Iot Console. This package contains navigation UI logic, and handles bootstrapping Microfrontend sub-tenants. You should be using the IotConsole/development versionset for your local workspace. Since you just ran bb start, you are now hosting a JS bundle at https://localhost:12898/. Congratulations! 🎉
You should now be looking to start developing either on this shell application, or a "subtenant" application of the console. Subtenants are broken down by features, like Device Defender, Greengrass, or IoT Device Management for instance.
