+---
+
+## Introduction
+
+The Documentation group maintains guidelines on terminology, grammar, formatting, inclusive language, document structuring, and image usage that are applied to the [Mendix Documentation](https://docs.mendix.com/) and the [Mendix Platform Evaluation Guide](https://www.mendix.com/evaluation-guide/).
+
+The guidelines can be referenced in these sections:
+
+* [Grammar & Formatting](grammar-formatting/)
+* [Terminology](terminology/)
+* [Inclusive Language](inclusive-language/)
+* [Structuring](structuring/)
+* [Images, Icons, and Videos](images-icons-videos/)
+* [Shortcodes, Markdown, and HTML](shortcodes-markdown-html/)
+* [Front Matter (Metadata)](front-matter/)
+* [Microcopy Guide](microcopy-guide/)
+* [Mendix Product Naming Guide](product-naming-guide/)
+
+The tone of the Mendix documentation is conversational, relaxed, and always straight-forward. The tone reflects the Documentation group's values.
+
+Our language conventions are based on American English.
+
+When editing the Evaluation Guide, you can use the WordPress shortcodes described in <https://mendix.atlassian.net/wiki/x/vwB2vg>
