The SD developers are working to provide documentation that is specific to SD. That documentation will be provided on this web site as it becomes available. However, much of the documentation for version 2.6.6 of OpenQM still applies to SD. An online version of the OpenQM 2.6.6 documentation can be found at https://scarl.cdmiweb.com/.
A variety of OpenQM 2.6.6 documentation can be downloaded from the Rushflat web site. You can access this documentation at https://www.rushflat.co.nz/multi-value.
For version 0.9.0 we have created a document that covers many of the additions, changes and deletions mades since ScarletDME was forked. Please note that this document is a work in progress. Some sections are not yet complete and additional sections may be added in the future. However, it allready gives good information on many of the changes and enhancements that have been made. This document is available here.
