Typo in config.edn example

I'm just beginning to learn this (and a total noob),
but I think the example code on http://cryogenweb.org/docs/configuration.html has a typo:
extra "}" in the end.

Open the configuration.html page at the linked documentation URL and find the config.edn example. Check the closing characters at the end of the example, remove the extra closing brace, and verify that the displayed configuration is syntactically correct.
