+scm or MIT/GNU Scheme in Sage
+=======================================
 
-in sage-###/devel/sage/sage/interfaces/, copy template.py to mitscheme.py 
-edit all.py and add appropriate objects, strings
+First install scm, MIT/GNU Scheme, or scmutils on your system. If you're doing
+scmutils do it in /usr/local/ as recommended.
 
-then compile everything:
-./sage -b 
+Then copy mitscheme.py and/or scm.py to SAGE_ROOT/devel/sage/sage/interfaces/
+and edit all.py to include the lines:
 
+    from mitscheme import mitscheme, mitscheme_console, MitScheme
+    from scm import scm, scm_console, SCM
 
+and edit the list of interfaces to include 'scm' and 'mitscheme'. For notebook
+cell use, edit SAGE_ROOT/devel/sage/server/notebook/notebook.py and add 
+'scm (optional)' and 'scmutils (optional)' to the list of interfaces.
 
+If you want plain mit-scheme instead of all the scmutils packages, edit
+mitscheme.py and replace the long 'command' declaration near the top with the
+short commented out declaration.
+
+Then return to your root sage directory (SAGE_ROOT) and do:
+
+    $ ./sage -b
+
+See if it works, eg:
+
+    sage: m = MitScheme()
+    Starting MIT/GNU Scheme Interpreter
+    sage: m.eval('(+ 1 1)')
+    '2'
+    sage: one = mitscheme(1)
+    '1'
+    sage: two = mitscheme(2)
+    '2'
+    sage: one + two
+    '3'
+
+Much to do!
