 DHQ articles are encoded using a customization of the [TEI Guidelines](https://tei-c.org). We are always grateful to authors who encode their own articles. You can find a [schema](https://github.com/Digital-Humanities-Quarterly/dhq-journal/blob/master/common/schema/DHQauthor-TEI.rng) and [encoding templates](https://github.com/Digital-Humanities-Quarterly/dhq-journal/tree/master/articles/templates) in this repository.
 
+[Our wiki](https://github.com/Digital-Humanities-Quarterly/dhq-journal/wiki) is home to a variety of helpful resources for authors and editors looking to endocde article files. [Consult the wiki](https://github.com/Digital-Humanities-Quarterly/dhq-journal/wiki) for encoding resources, topic area keyword descriptions, and development or data management notes.

 The DHQ journal is published using a custom publication system based on the Apache Cocoon framework, with XSLT, CSS, and JavaScript. The stylesheets and other code are available in this repository. If you have an idea for improving the DHQ interface and would be interested in contributing to the journal’s development, we would love to hear from you! Please email us.
