no such readme needed now that all it takes to run Hudson for debugging is "mvn jetty:run".

core/README.txt

-For efficient debugging, set the system property "stapler.jelly.noCache" to true on the container.
-For example in Tomcat, this can be done by:
-
-  $ export CATALINA_OPTS="-Dstapler.jelly.noCache=true"
-  $ catalina.sh run
-
-This setting tells Stapler not to cache compiled Jelly scripts, so every change you make to
-Jelly scripts will be reflected instantly without reloading the whole app (at the expense
-of slow page rendering performance.)
