+# Experimental module
+
+The purpose of this module is to hold contracts/cordapps that aren't yet ready for code review, but which still want
+to be refactored and kept compiling as the underlying platform changes. Code placed into experimental *must* eventually
+either be moved into the main modules and go through code review, or deleted.
+
+Code placed here can be committed to directly onto master at any time as long as it doesn't break the build
+(no compile failures or unit test failures). Any commits here that break the build will simply be rolled back.
