+
+To make development and customization easier, gnosis comes with
+@samp{gnosis-dev} module, that should be used to create a custom database for
+testing.
+
+To use @samp{gnosis-dev}, first you have to @samp{(require 'gnosis-dev)} & run @samp{M-x
+gnosis-dev-test}. This will create a new directory 'testing' with a new
+database.
+
+To exit the testing environment, rerun @samp{M-x gnosis-dev-test} and then
+enter @samp{n} (no) at the prompt ``Start development env?''
