This notebook assumes that the reader is already familiar with MuJoCo basic concepts, as demostrated in the [introductory tutorial](https://github.com/google-deepmind/mujoco?tab=readme-ov-file#getting-started). Documentation for this API can be found in the [Model Editing](https://mujoco.readthedocs.io/en/latest/programming/modeledit.html) chapter in the documentation (C API) and in the [Python chapter](https://mujoco.readthedocs.io/en/latest/python.html#model-editing).
