+Fields are used by the serializers for the data. We have our fields specified in module `core.fields`. These fields are `rest_framework` fields.
+
+
+## Char Field
+
+This field extends `rest_framework.serializers.CharField` with additional attributes that are used by the UI. The additional attributes are:
+
+- `autolink`, _Boolean_ The interface will render the field as an anchor using the url at path `_urls._self` of the objects data.
+
+- `multiline`, _Boolean_. The field should be rendered as a `textarea` input field.
+
+if attribute `multiline` is not specified, by default the field is rendered as an input text field.
+
+
+## Markdown Field
+
+This field extends `core.fields.CharField`. The field metadata sets the field type to `Markdown`, which tells the UI to render the field as markdown. The additional attributes are:
+
+- `multiline`, _Boolean_. The field should be rendered as a `textarea` input field.
+
+- `style_class` _String_ This field is a space seperated value (ssv) of CSS classes to use for the field. The UI will use this value as additional CSS classes to append to the field.
