 # Rendered math (MathJax) with Slack's desktop client
 
-[Slack](https://slack.com) does not display rendered math. This script injects [MathJax](https://www.mathjax.org) into Slack's desktop client, which allows you to write nice-looking inline- and display-style math using familiar TeX/LaTeX syntax. You can also edit equations after you've posted them.
+[Slack](https://slack.com) does not display rendered math. The `math-with-slack` script allows you to write nice-looking math using familiar TeX syntax by injecting [MathJax](https://www.mathjax.org) into Slack's desktop client. This approach has several advantages over the plugin/bot solution:
+
+  * You can write both inline- and display-style equations.
+  * You can edit equations after you've posted them.
+  * Nothing is sent to external servers for rendering.
+
+The downside is that equations are not rendered for team members without the MathJax injection.
