+To run a tutorial, start emacs/slime or your CL Lisp in the common-lisp/clog directory:
+
+```
+CL-USER> (ql:quickload :clog)
+To load "clog":
+  Load 1 ASDF system:
+    clog
+; Loading "clog"
+...........................
+(:CLOG)
+```
+
+Load the demo:
+
+```
+CL-USER> (load "/Users/dbotton/common-lisp/clog/tutorial/01-tutorial.lisp")
+#P"/Users/dbotton/common-lisp/clog/tutorial/01-tutorial.lisp"
+```
+
+Start the demo:
+
+```
+CL-USER> (clog-user:start-tutorial)
+Hunchentoot server is started.
+Listening on 0.0.0.0:8080.
+HTTP listening on : 0.0.0.0:8080
