-## Install From Repository
+## When you need a Qt backend
+
+Before `v5.1`, Manim Slides automatically included PySide6 as
+a Qt backend. As only `manim-slides present` and `manim-slides wizard`
+command need a graphical library, and installing PySide6 on all platforms
+and Python version can be sometimes complicated, Manim Slides chooses
+**not to include** any Qt backend.
+
+The use can choose between PySide6 (best) and PyQt6, depending on their
+availability and licensing rules.
+
+As of `v5.1`, you **need** to have Qt bindings installed to use
+`manim-slides present` or `manim-slides wizard`. The recommended way to
+install those are via optional dependencies, as explained above.
+
+## Install from source
 
 An alternative way to install Manim Slides is to clone the git repository,
