First of all, Pimcore is more or less a standard Symfony application, so most of the Symfony best-practices also apply for Pimcore. It's highly recommended to have a detailed look at them before you deploy a Pimcore application to production.
This section documents definable topics or stories which are too unique or special to fit into the main documentation tree. In many implementations of Pimcore our partners and community develop features, which can also be useful for other implementations. The Pimcore core team will release new articles on a regular basis as well.
If you would like to contribute, just submit a new article as a pull request. See the contribution guideslines on how to do that.
