+## Variables
+
+An example of the GraphQL needed to create an advanced task is available in 
+createDumpSanitisedDB.gql.  The variables which can be passed in are also 
+documented in this file (in the "displayName" field of each entry).  
+
+## Process
+
+The process goes through X basic stages:
+
+1. Set up all the initial variables
+2. MTK creates a database dump that's basically a sanitised .sql file
+3. Make docker-style container with sanitised DB (using podman)
+4. Save new container to registry
