    To generate a lightweight GUI interface, you can add the ``--gui`` flag to your
    analysis command.
 
+   Analyze mode now supports a lightweight Text-based User Interface (TUI) that
+   provides an interactive terminal experience for enhanced usability. To enable TUI mode,
+   use the ``--tui`` flag when running the analyze command:
+
+   .. code-block:: shell
+
+      $ rocprof-compute analyze --tui

    This mode is a middle ground to the highly detailed ROCm Compute Profiler Grafana GUI and
    is great if you want immediate access to a hardware component you’re already
    familiar with.
