# Introduction

This guide is intended for Isomer sites that were:

1. Created prior to the implementation of IsomerCMS, and 
2. Were not designed to be editable via the CMS

If your Isomer site was created after 2021, this guide is not applicable to you. Please refer to our [main guide](/configurations/contact-us.md) for more information.

This guide will eventually be phased out and taken down, following the launch of IsomerCMS
