Now available via Umbraco docs https://our.umbraco.com/documentation/Tutorials/Editors-Manual/
The editors manual is a detailed yet easy to read user guide aimed at Umbraco editors for step-by-step instructions on performing every day tasks with Umbraco 7. It assumes no prior knowledge of Umbraco and provides a brief introduction and explanation of the overall interface. The manual covers the most common tasks an editor would likely face providing clear instructions and helpful guidance.
It is useful as both a training guide as well as a quick reference for editors working with Umbraco.
The manual is based on the original Umbraco 4/6 manual managed by Matt Brailsford which can be found at http://our.umbraco.org/projects/website-utilities/editors-manual . This new manual has been overhauled and re-written from the ground up for Umbraco 7.
The manual was written and is maintained by CAB Studios (http://www.cabstudios.co.uk/). We hope to eventually get the manual into an editable format for colloboration but for the time being we welcome any and all feedback and will look to update the manual as and when required.
Please note, this is a PDF file only for use as a training manual/guide and is not an installable package.
