2. If you are adding code, ensure the changed notebooks can be run in a fresh environment. Include instructions to download
any additional dependencies.
3. Ensure any spurious changes are removed, such as compilation files (`pyc`) or metadata changes in a notebook.
You can automatically do so using nbstripout:
```
pip install nbstripout
nbstripout --install
```
This will install a git hook that strips all metadata from the notebooks before you commit changes to git.
4. Submit your pull request on GitHub.
5. A member of the GSI-UPM group will review your request.
6. The reviewer may ask for further changes before merging the contribution. Please, follow the reviewer's instructions before resubmitting.
