+# FAQ
+* Q: "Why are the names of the modules using underscore instead of hyphens?"
+  A: The modules are best deployed through the [R10k](https://github.com/puppetlabs/r10k) service using a Puppetfile. The deployment process using Puppetfile would convert the name of say "confdroid-postgresql" into a module called "confdroid" locally on the puppet server, cutting off everything after the hyphen. It also would then not deploy more than one module, because they all would be called "confdroid"
