+```{warning}
+The instructions provided here are stable, but because it relies on a local extension that is part of your book files and _not_ managed as part of a computing environment (e.g., `pip` or `conda`), there may be incompatibility with other features. For example, the draft-release workflow does not work.
+
+We are actively working on improving this. Visit the [project page on GitHub](https://github.com/orgs/TeachBooks/projects/17) to learn more.
+
+This page will be updated when a solution is available.

 ## Introduction
 
-This extension allows you to have APA formatting which is not a default option.
+Do you include references in your book, but you're tired of the default options available in Jupyter Book? For example, the square-bracket style of citation and reference, where the first three letters of the name year are combined in a way that seems designed to minimize transparency?
+
+There is a solution! This extension allows you to have APA formatting in your book.
 
 ## Installation

 ## Usage
-All references are now made in APA-style. See for example this reference: {cite}`jason_moore` which shows up on the [references page](../references.md) too.

-### Known issue
-During the build, warning will be raised with `... WARNING: duplicate label for keys ...`. In most cases, these warnings can be ignored.
+### Known Issue
+
+During the build, warning will be raised with `... WARNING: duplicate label for keys ...`. In most cases, these warnings can be ignored. As noted above, the book will not build references properly 
+
+## Implementation
+
+The extension is based on [`pybtex`](https://pybtex.org/), which is a BibTeX-compatible bibliography processor in Python that is extendible with plugins. 
+
+Although some customization is possible with the standard Jupyter Book features, [as described here](https://jupyterbook.org/en/stable/content/citations.html#change-the-in-line-citation-style), this extension implements the complete APA style, as well as enforcing round brackets (like this).
+
+The need to enforce `docutils==0.17.1` version is the only known solution to the issue where empty brackets `[]` are left on the references page.
