-Experimental TUI
-================
-
-A TUI is a "text user interface" (or "terminal user interface") - a keyboard and mouse driven graphical interface running in your terminal.
-
-``sqlite-utils`` has experimental support for a TUI for building command-line invocations, built on top of the `Trogon <https://github.com/Textualize/trogon/>`__ TUI library.
-
-To enable this feature you will need to install the ``trogon`` dependency. You can do that like so:
-
-.. code-block:: bash
-
-    sqlite-utils install trogon
-
-Once installed, running the ``sqlite-utils tui`` command will launch the TUI interface:
-
-.. code-block:: bash
-
-    sqlite-utils tui
-
-You can then construct a command by selecting options from the menus, and execute it using ``Ctrl+R``.
