 VitePress will be configured with an `alias` to allow you to access your library within the documentation. This will use the library source code directly, without needing a build or release of the library.
 
+## Include support for vp-raw in VitePress?{#include-vp-raw}
+
+:::info NOTE
+You'll only see this question if you chose to include VitePress *and* you're using the `--extended` flag.
+:::
+
+The default theme for VitePress can potentially clash with the CSS for components in your library. This is especially problematic when using Tailwind.
+
+To mitigate this, VitePress supports the use of a `vp-raw` CSS class (or a `raw` custom container) to isolate component examples from the default VitePress styling:
+
+- <https://vitepress.dev/guide/markdown#raw>
+
+Isolating the styles will increase the size and complexity of the documentation CSS, so VitePress doesn't enable it by default. Instead, it must be enabled via a PostCSS plugin.
+
+If you choose to include support for `vp-raw` then PostCSS will be added to the documentation package, along with the relevant configuration to enable style isolation.
+
+This option will default to **Yes** if the project is using Tailwind.
