#### Introduction
This sample showcases how to build a comment section in AMP HTML using the [amp-form](https://www.ampproject.org/docs/reference/components/amp-form) component after a successful login flow. Login, type a comment and press the COMMENT button; your comment will not be persisted, so reload the page if you want to start commenting again.

<!-- [amp-access](/components/amp-access) requires the definition of 3 endpoints as documented [here](https://www.ampproject.org/docs/reference/components/amp-access). This sample allows an user to login and logout: this is realized by specifying two different endpoints in the login property, `sign-in` and `sign-out`, find more [here](https://www.ampproject.org/docs/reference/components/amp-access#login-page)-->

the endpoint. -->
