Extend documentation

Thanks, you're totally right. Could you improve that perhaps?

It doesn't need technical knowledge and is a community job. Thank you

Sure, will be happy to provide an update to the Readme. Can you point me to the admin page for this first step "On the order form display enable the checkout form mode."? I was not able to get the module working yet.

Finally, I got it working. Can you add the following to the project description? Issue 3133317 → can be closed then, too.

Requirements:
Please make sure that you have activated the "Fields UI" extension.

Configuration:
Open your order type in commerce configuration and switch to tab "Manage fields" (e.g. /admin/commerce/config/order-types/default/edit/fields).
Now add the fields that you wish to add to your checkout process. E.g. add a "Text (plain, long)" field to allow users to provide order comments.
You can create multiple fields but they will appear all at one defined location in the checkout process later.

Next the display of the fields is configured. Switch to tab "Manage form display" (e.g. /admin/commerce/config/order-types/default/edit/form-display).
Here activate the custom display settings for "Checkout" at the end of the page. Then save.
Now you can edit the "Checkout" display settings (e.g. /admin/commerce/config/order-types/default/edit/form-display/checkout).
Here disable all fields except your new fields.

Finally, you can specify where the new fields should be displayed. This is on the checkout flow configuration page (e.g. /admin/commerce/config/checkout-flows/manage/default).
Move the pane "Order fields: Checkout" to the right section, e.g. "Review".

Now you should see your new fields during the checkout process.

Thanks @gruberroland! Sorry I wasn't able to reply earlier.

Please make sure that you have activated the "Fields UI" extension.

What's the reason for that? We should add a dependency, if the module isn't working without it. Is that the case? Did you run into an issue?

If you can add a dependency then even better. The Fields UI module provides the GUI to manage fields. Without it there is no tab to manage any fields.

@gruberroland please review :)

Thanks, looks good! :)

Could you set the status to RTBC then please, so I may merge it?

Thanks! Merged and credited! :)
