 These are the instructions for building the Python bindings for KDDockWidgets.
 
+Currently unsupported:
+
+- debug builds
+- builds against Qt debug libraries
+- static builds
+- python2 bindings
+- only some 32-bit platforms are supported.  see <https://wiki.qt.io/Qt_for_Python>
+
+Also, there are no plans to support the qmake buildsystem.
+
+## Prerequisites
+
+You will need:
+
+- a compiler with C++14 support (C++17 for Qt6 builds)
+- Python3.7 or higher
+- Qt5 version 5.12 or higher
+- Qt6 version 6.2 or higher
+- QtForPython provided by the Qt project.

+## Install PySide2 for Qt5

 Make sure you have PySide2, shiboken2 and shiboken2-generator installed.
 As this time, you cannot get shiboken2-generator because the wheels are not on PyPi.

+## Building KDDockWidgets Python Bindings
 
-The bindings will be installed to the passed `-DCMAKE_INSTALL_PREFIX`, which
-might require setting the `PYTHONPATH` env variable to point to that path when
-running applications.  Alternatively, configure the bindings install location
-by passing `-DKDDockWidgets_PYTHON_BINDINGS_INSTALL_PREFIX=/usr/lib/python3.8/site-packages`
-to CMake (adjust to the python path on your system).
+Tell CMake to build the bindings by passing the `-DKDDockWidgets_PYTHON_BINDINGS=True' option.
+Then run `cmake --build` as usual.
+
+The bindings will be installed to `CMAKE_INSTALL_PREFIX`, which might require setting
+the `PYTHONPATH` env variable to point to that path when running applications.
+
+For example, if you install to the default location on linux you would:
+
+```bash
+  export PYTHONPATH=/usr/local/KDAB/KDDockWidgets-1.7.0/lib64/python3.10/site-packages
+```
+
+Alternatively, configure the bindings install location by passing (for example)
+`-DKDDockWidgets_PYTHON_BINDINGS_INSTALL_PREFIX=/usr/lib/python3.8/site-packages` to CMake
+and adjust to the PYTHONPATH accordingly, as necessary.
