+### Terminal User Interface (TUI)
+
+`rattler-build` offers a terminal user interface for building multiple packages and viewing the logs.
+
+![rattler-build-tui](https://github.com/prefix-dev/rattler-build/assets/24392180/52138fd0-3c53-4028-a2c8-3099222c368a)
+
+To launch the TUI, run the `build` command with the `--tui` flag as shown below:
+
+```shell
+$ rattler-build build -r recipe.yml --tui
+```
+
+> [!NOTE] > `rattler-build-tui` is gated behind the `tui` feature flag to avoid extra dependencies. Build the project with `--features tui` arguments to enable the TUI functionality.
