Add "help" to page creation

[iriseel]

I’d like to add a “help“ or instructional note to the page creation popup for my project.yml. Is there a way to do this? Since we can’t set maxLength on the Title of a project, I’m hoping to be able to at least remind the user that they should limit their titles when naming a new project. I’ve been able to display a “help“ line before with the following:

create:
  slug: "{{ page.title.slug }}-{{ page.published.toDate('Ymd') }}"
  fields:
    - published

// later on
published:
                    label: Published on
                    help: Make sure you pick the correct published date now, as this will be appended to the page url itself. If you change the published date later, you will need to update the url manually.
                    type: date
                    default: now

But so far, modifying the code for my new use case has only produced errors:

create:
  title: "{{ page.title }}"
  fields:
    - title

// Later on 

fields:
                  Title:
                    type: text
                    required: true
                    help: Make sure the title does not exceed 50 characters, or else it will not display properly on the page.

Your new case it a bit confusing as you set a template for the title page.title but then want to add the field itself again? You can just do this instead:

create:
  title:
    help: Your help text

Another option is also to use an info field and add it to the create dialog to display additional explanations.
