+If you're using [ratatui][] instead of [tui-rs][], you need to enable features for using ratatui crate. The following table
+shows feature names corresponding to the dependencies.
+
+|         | crossterm                        | termion           |
+|---------|----------------------------------|-------------------|
+| tui-rs  | `crossterm` (enabled by default) | `termion`         |
+| ratatui | `ratatui-crossterm`              | `ratatui-termion` |
+
+For example, when you want to use [ratatui][] and [crossterm][],
+
+```toml
+[dependencies]
+ratatui = "*"
+tui-textarea = { version = "*", features = ["ratatui-crossterm"] default-features=false }
+```
+
+**Note:** [tui-rs][] support and [ratatui][] support are exclusive. When you use [ratatui][] support, you must disable
+[tui-rs][] support by `default-features=false`.
+
+**Note:** Versions of [crossterm][] crate are different between [tui-rs][] and [ratatui][]. Please choose correct version
+of the crate as dependency of your project.
