+Alright, you learned about the [manifest](creating_integration_manifest.md), so it's time to write your first code for your integration. AWESOME. Don't worry, we've tried hard to keep it as easy as possible. From a Home Assistant development environment, type the following and follow the instructions:

-## The code
+This will set you up with everything that you need to build an integration that is able to be set up via the user interface. More extensive examples of integrations are available from [our example repository](https://github.com/home-assistant/example-custom-config/tree/master/custom_components/).
 
-Each component needs to have 2 basic parts: it needs to define a `DOMAIN` constant that contains the domain of the integration. The second part is that it needs to define a setup method that returns a boolean if the set up was successful. So let's take a look at how this looks:
+## The minimum

+The scaffold integration contains a bit more than just the bare minimum. The minimum is that you define a `DOMAIN` constant that contains the domain of the integration. The second part is that it needs to define a setup method that returns a boolean if the set up was successful.
 
 ```python
 DOMAIN = 'hello_state'

-That's it! If you load this, you will see a new state in the state machine.

 To load this, add `hello_state:` to your `configuration.yaml` file and create a file `<config_dir>/custom_components/hello_state/__init__.py` with one of the two codeblocks above to test it locally.

+## What the scaffold offers
+
+When using the scaffold script, it will go past the bare minimum of an integration. It will include a config flow, tests for the config flow and basic translation infrastructure to provide internationalization for your config flow.
