+## Sliders not dragging properly on MacOS 12+
+
+??? details
+    On MacOS Monterey, with Qt5, there is a bug that causes all sliders
+    (including native Qt sliders) to not respond properly to drag events.  See:
+
+    - [https://bugreports.qt.io/browse/QTBUG-98093](https://bugreports.qt.io/browse/QTBUG-98093)
+    - [https://github.com/napari/superqt/issues/74](https://github.com/napari/superqt/issues/74)
+
+    Superqt includes a workaround for this issue, but it is not perfect, and it requires using a custom stylesheet (which may interfere with your own styles).  Note that you
+    may not see this issue if you're already using custom stylesheets.
+
+    To opt in to the workaround, do any of the following:
+
+    - set the environment variable `USE_MAC_SLIDER_PATCH=1` before importing superqt
+    (note: this is safe to use even if you're targeting more than just MacOS 12, it will only be applied when needed)
+    - call the `applyMacStylePatch()` method on any of the superqt slider subclasses (note, this will override your slider styles)
+    - apply the stylesheet manually:
+
+    ```python
+    from superqt.sliders import MONTEREY_SLIDER_STYLES_FIX
+
+    slider.setStyleSheet(MONTEREY_SLIDER_STYLES_FIX)
+    ```

+[PySide](https://www.qt.io/qt-for-python) that are not provided in the native
+QtWidgets module.
+
+Components are tested on:
+
+- macOS, Windows, & Linux
+- Python 3.7 and above
+- PyQt5 (5.11 and above) & PyQt6
+- PySide2 (5.11 and above) & PySide6
+
+## Installation
+
+```bash
+pip install superqt
+```
+
+```bash
+conda install -c conda-forge superqt
+```
+
+## Usage
+
+See the [Widgets](./widgets/) and [Utilities](./utilities/) pages for features offered by superqt.
