MyLife version 4 uses the Umbraco Content Managment System (CMS).
This is an application to create and change the site content (pages with widgets, articles, images, documents, etc.) and settings.
OLM Systems, the provider of the website platform, have produced a set of guidance and documents to help get you up and running with common tasks.
The guide can be found at https://docs.mylifetest.co.uk/v4.
If you are new to MyLife or Umbraco, then you should start with the orientation – https://docs.mylifetest.co.uk/v4/orientation.
Otherwise you can jump straight into a chapter using the menu or search – visit https://docs.mylifetest.co.uk/v4.
