+This is currently still in development as I mess around with creating objects in Blender using Python scripts.
+
+This has been built using:
+- version 2.82a of Blender ([Blender downloads](https://www.blender.org/download/)).
+- Ubuntu 18.04 (This will be relevant writing your filepath)
+
+Credit to @cly_faker for the process from [this video](https://www.youtube.com/watch?v=nCowrvfOr3Q)
