+Desktop
+=======
+
+This folder contains everything needed to create file associations and icons to
+present BlenderBIM as a desktop application.
+
+Linux
+-----
+
+Assuming that blender and BlenderBIM are already installed on your system,
+configure associations and icons for a single user by running `make`:
+
+  make install
+
+Test by running the wrapper script directly, this should launch BlenderBIM with
+an empty IFC project:
+
+  blenderbim.sh
+
+This `Makefile` installs files to `~/.local` by default, to install to an
+alternative location, set `DESTDIR`:
+
+  sudo make install DESTDIR=/usr/local
+
+### `command not found` error
+
+If you have downloaded and installed blender from blender.org, then blender may
+not be findable via your `PATH` environment variable.
+
+Either add the folder containing the `blender` executable to your `PATH`, or
+set the `BLENDER_EXE` environment variable to the location of the `blender`
+executable.
+Instructions will vary depending the linux distribution, consult your documentation.
+
+Windows
