In order to help developers integrate this module with an existing website, the module provides templates that can be used.
When the module is installed, a new authenticator is registered which allows the login form to show a template for RealMe login.
RealMe have some strict rules for how you present the RealMe login functionality, please see the instructions on the RealMe Developers site for complete details.
Along with the standard large-form login forms, there is also a 'mini' login form, suitable
for use in the header and footer of websites. This can be included by adding a method to your
normal Page_Controller that returns a new SilverStripe\RealMe\Authenticator\MiniLoginForm($this, __FUNCTION__);. This
form uses GET rather than POST, so is an extension of the normal login form. This bypasses
the requirement to go to Security/login, so is only useful when it is the only method of
login to a website.
Further documentation on using these templates can be found in the template files themselves: RealMeLoginForm.ss and RealMeLoginForm_secondary.ss.
