 	    FreeBSD maintainer's guide to OpenSSH-portable
 	    ==============================================
 
+    These instructions assume you have a clone of the FreeBSD git repo
+    main branch in src/freebsd/main, and will store vendor trees under
+    src/freebsd/vendor/.  In addition, this assumes there is a "freebsd"
+    origin pointing to git(repo).freebsd.org/src.git.
+
 00) Make sure your mail spool has plenty of free space.  It'll fill up
     pretty fast once you're done with this checklist.
