-## Reusable Libraries
-
-When publishing a library designed to work with Dioxus, we highly advise using only the core feature on the `dioxus` crate. This makes your crate compile faster, makes it more stable, and avoids bringing in incompatible libraries that might make it not compile on unsupported platforms.
-
-
-❌ Don't include unnecessary dependencies in libraries:
-```toml
-dioxus = { version = "...", features = ["web", "desktop", "full"]}
-```
-
-✅ Only add the features you need:

 ## Notes
 
 - Our TUI package uses flexbox for layout
+- Regular widgets will not work in the tui render, but the tui renderer has it's own widget components (see [the widgets example](https://github.com/DioxusLabs/dioxus/blob/master/packages/tui/examples/tui_widgets.rs)).
 - 1px is one character lineheight. Your regular CSS px does not translate.
