+# Font Awesome extension for Quarto
+
+This extension allows you to use [Font Awesome](https://fontawesome.com/) icons in your quarto documents. 
+
+## Installation
+
+From the command line, at the root directory of your quarto project:
+
+```
+$ quarto install extension https://github.com/quarto-dev/quarto-ext/fontawesome
+```
+
+This will install the extension under the `_extensions` subdirectory.
+If you're using version control, you will want to check in this directory.
+
+## Usage
+
+This extension provides the `fa` shortcode:
+
+```
+{{< fa icon-name >}}
+```
+
+For example, here's a minimal full document that uses Font Awesome icons in both PDF and HTML:
+
+    ---
+    format:
+        pdf: default
+        html: default
+    ---
+
+    This is a test. {{< fa book >}} {{< fa download >}}
+
+## Known Issues
+
+* The PDF format uses fontawesome5, while the HTML format uses fontawesome6.
+* No formatting 
\ No newline at end of file
