+# The "content" app
+
+This application serves static, Markdown-based content. Django-wise there is
+relatively little code in there; most of it is concerned with serving our
+content.
+
+
+## Contributing pages
+
+The Markdown files hosting our content can be found in the
+[`resources/`](./resources) directory. The process of contributing to pages is
+covered extensively in our online guide which you can find
+[here](https://www.pythondiscord.com/pages/guides/pydis-guides/how-to-contribute-a-page/).
+Alternatively, read it directly at
+[`resources/guides/pydis-guides/how-to-contribute-a-page.md`](./resources/guides/pydis-guides/how-to-contribute-a-page.md).
+
+
+## Directory structure
+
+Let's look at the structure in here:
+
+- `resources` contains the static Markdown files that make up our site's
+  [pages](https://www.pythondiscord.com/pages/)
+
+- `tests` contains unit tests for verifying that the app works properly.
+
+- `views` contains Django views which generate and serve the pages from the
+  input Markdown.
+
+As for the modules, apart from the standard Django modules in here, the
+`utils.py` module contains utility functions for discovering Markdown files to
+serve.
