Update with instructions on how to use options like "description" and fields in content types.

The documentation should be updated to explain how to use all of the different fields like "description". I can't find anything in the documentation that explains it and every way I try to use it as a field in contenttypes.yml creates an error when I try to check my database.

The list is here:
https://docs.bolt.cm/contenttypes-and-records
And on the cheat sheet.

**Two of the ways I've tried are contenttype.yml usage as:**

``` apps:
name: Apps
singular_name: Appitem
fields:
description: "Useful applications for people with Mast Cell Disease."
title:
type: text
class: large
```

**or**

``` apps:
name: Apps
singular_name: Appitem
description: Useful applications for people with Mast Cell Disease.
fields:
```

**The error is generally this:**
In the contenttype for 'Appitem', the field 'description' has 'type: ', which is not a proper field type. Please edit contenttypes.yml, and correct this.

**Fields**

Simple instructions such as how to use multiple text fields in the same content type should be added. I thought every field that I wanted to be a :text just needed a different label to be pulled into the records.twig template. Online I was told that every one needed a new ID, but I'm still not sure this is correct because every field that doesn't have the ID "text" is pulled into the template differently. The front end will only show their ID string and content.

**My example is:**

``` text:
type: html
height: 300px
text2:
type: text
text3:
type: text
```

**Text 2 and 3 are shown on the front end as:**

**text2:** Text2 Content

**text3:** Text3 Content

There should be something that says "To edit the way extra fields are shown on the front end please follow this link..."

I can write this myself for use if I could figure out how to do it. But I can't find it in the documentation and I've gone over it many times. If I'm missing something important I'm really sorry, but I've tried finding and searching.
