+Bundling with Blender
+---------------------
+
+Blender is bundled with a version of BAM. To update this version, first build
+a new `wheel <http://pythonwheels.com/>`_ file::
+
+    python3 setup.py bdist_wheel
+
+Then copy this wheel to Blender::
+
+    cp dist/blender_bam-*.whl /path/to/blender/release/scripts/addons/io_blend_utils/
+
+Remove old wheels that are still in `/path/to/blender/release/scripts/addons/io_blend_utils/`
+before committing.
+
+
+Running bam-pack from the wheel
+-------------------------------
+
+This is the way that Blender runs bam-pack::
+
+    PYTHONPATH=./path/to/blender_bam-*.whl python3 -m bam.pack
