+#### Theme customization
+
+Chitchatter utilizes the [MUI component library](https://mui.com/) which is [themeable](https://mui.com/material-ui/customization/theming/). You can customize Chitchatter's look and feel by modifying [the shell theme definition](https://github.com/jeremyckahn/chitchatter/blob/dc78137702bb9d6bf1be289e469e080cd7d5dc8b/src/components/Shell/useShellTheme.ts#L11-L18).

 ### Troubleshooting
 
 If you run into any issues with a custom Chitchatter installation, first ensure that you are using [the latest version of the code](https://github.com/jeremyckahn/chitchatter/tree/main). If you are hosting your installation with GitHub Pages, sync your `main` branch and _not_ your `gh-pages` branch. Updating your `main` branch will trigger a proper rebuild of your `gh-pages` branch.
