+Docsy supports top-down Right-To-Left (RTL) languages such as Persian through
+[Bootstrap's RTL feature][bs-rtl], which uses [RTLCSS].

+If your multilingual site includes an RTL language (configured with
+`languageDirection: rtl`), then your project needs to include the [`rtlcss`
+package]. You can add this package to your dev dependencies as follows:

+```sh
+npm install rtlcss --save-dev
