+
+Since the orderList.tsv listings have become very large, it has
+become inconveniently time consuming to run through the standard
+process as described below.  There is a newer 'minimal build' procedure
+in use now that can save a lot of time.
+
+At the point where you have added your new assembly to the orderList.tsv
+file, instead of running through the full sequence of make commands
+for the entire clade set you are working on, go to the clade directory and
+run:
+
+   time (../asmHubs/minimalBuild.sh) > minimal.log 2>&1
+
+and that script will run the make commands on only the new assemblies
+in the orderList.tsv.  It still takes a long time (hours) to do part of that
+job when it is making up the clade index.html files, but much of the
+time consuming working through every assembly in the list is eliminated.

 ### Requests from the request system:
 
 When a user sends in a request with an accession ID, e.g.: GCF_002776525.5
 the assembly may already exist in some version.  To check if something
 already exists, use just the number part of the ID: 002776525 and
 check the existing listings in the source tree:
 
     grep 002776525 ~/kent/src/hg/makeDb/doc/*AsmHub/*.tsv
 
 They may be asking for a newer version, or they may be asking for
 a GenBank version when a RefSeq version already exists.  Can decide
 if what we have is better than what they ask for.  True, sometimes they
