Steps
Run the python3 -m script.scaffold config_flow (or config_flow_discovery) tool in a Home Assistant core dev environment to generate integration boilerplate.
Fill in manifest.json fields: domain, name, codeowners, documentation, iot_class, requirements, and set config_flow: true to enable UI setup.
Implement a config_flow.py that subclasses ConfigFlow and defines async steps (e.g. async_step_user) for each UI screen.
Define the field labels/descriptions for each config flow step in strings.json (and translations if needed).
Test the integration by adding it through Settings > Devices & Services in the UI and confirming the config flow screens render correctly.
Known gotchas
The domain value in manifest.json cannot be changed after devices are set up with it without breaking existing config entries.
Forgetting to keep strings.json in sync with the steps defined in config_flow.py results in blank or missing labels in the UI setup wizard.
