 We provide [an official Docker image in the GitHub Container Registry](https://github.com/orgs/voxpupuli/packages/container/package/puppetboard).
 
+You must provide a secret key! Generate one for example by running `ruby -e "require 'securerandom'; puts SecureRandom.hex(32)"`.

 You can run the app on your PuppetDB host with this command:
