+
+### Email details
+
+#### Email Subject
+
+The subject of the email, you can either type a custom subject here or select a field from the form to use as the email subject.
+
+#### Send email to
+
+This is the recipient's address where the email will be sent.
+
+#### Send email from
+
+This shows where the email was sent from, and will most likely need to be an email address on the same domain as your site. For example If your website is yoursite.com, the email address for this field should be something@yoursite.com.
+
+#### Email for reply to
+
+This will be the address which the email recipient will be able to 'reply' to.
+
+#### Email content
+
+In this field you can add a custom message to add to the email
+
+#### Hide form data from email?
+
+You can check this if you do not wish for the email recipient to see the form submission's data in the email.
+
+#### Send email as plain text?
+
+You can check this if you want to remove all of the HTML from the email, this means the email
+will have no custom styling and the recipient will only see the plain text.
+
+If `Send email as plain text?` is unselected, several additional options for HTML editing are displayed.
+
+If sending as HTML, there is the option to preview the HTML that is sent in the editor. Additionally, a HTML
+template can be selected to provide a standard formatted email to contain the editable HTML content.
+
+The list of available templates can be controlled by specifying the folder for these template files in yaml config.

+	  email_template_directory: mysite/templates/useremails/
+
+
+### Custom Rules
+
+In this section you can determine whether to send the email to the recipient based on the data in the form submission.
+
+#### Send conditions
+
+This decides whether to send the email based on two options
+
+1. *All* conditions are true (Every single custom rule must be met in order to send the email)
+2. *Any* conditions are true (At least one of the custom rules must be met in order to send the email)

+* Click 'Add' to add a custom sending rule.
