+Raspberry Pi
+====================
+
+Please use Raspberry Pi OS Bullseye.  Older OSes are not tested.
+
+We have published a binary wheel using Raylib in X11 mode.  This *should* install and work on Bullseye
+with
+
+::
+
+    python3 -m pip install raylib==4.2.0.0.dev1
+
+If it doesn't work, or we haven't published a binary wheel for the latest version,
+or if you want to use Raylib in ``PLATFORM_DRM`` mode, you will need to compile your own raylib
+and have pip compile the wheel.
+
+::
+
+    git clone https://github.com/raysan5/raylib.git
+    cd raylib
+    mkdir build
+    cd build
+    cmake -DPLATFORM="DRM" -DINCLUDE_EVERYTHING=on -DSUPPORT_FILEFORMAT_JPG=on -DWITH_PIC=on -DCMAKE_BUILD_TYPE=Release ..
+    make
+    sudo make install
+    pip3 install --no-binary raylib --upgrade --force-reinstall raylib==4.2.0.0.dev2
+
+(or newer version)
+
+.. attention::
+
+    The Broadcom proprietary Open GL ES 2.0 drivers (installed by Raspbian into ``/opt/vc`` and compiled in Raylib
+    with ``PLATFORM_RPI``) do not work with Bullseye and have not been tested with the bindings.  They will probably
+    require additional linker arguments to be added to ``build.py``.  Suggest you use ``PLATFORM_DRM`` instead.
