 When building the documentation locally you will need to have installed [pandoc](https://pandoc.org/installing.html) and [gifsicle](https://github.com/kohler/gifsicle).
 We recommend installing pandoc using its Anaconda distribution: `conda install -c conda-forge pandoc`.

+**NOTE:** it may be expedient at times to avoid running the tutorial notebooks. To do so, add [`nbsphinx_execute = 'never'`](https://nbsphinx.readthedocs.io/en/0.9.3/configuration.html#nbsphinx_execute) to `docs/source/conf.py`. Make sure not to commit these changes!
 
- 1. **Avoid running the tutorial notebooks:** Add [`nbsphinx_execute = 'never'`](https://nbsphinx.readthedocs.io/en/0.9.3/configuration.html#nbsphinx_execute) to `docs/source/conf.py`
- 2. **Disable the link check operation:** Comment out the `linkcheck` call in `docs/build_docs.py`

+If you add or change any hyperlinks in the documentation, we recommend checking the "Build documentation" warnings in the GitHub Actions CI workflow to make sure the links will not cause an issue. The CI will not fail due to broken links, only issue a warning (see [issue #286](https://github.com/sandialabs/WecOptTool/issues/286)).
 
 ### Editing the tutorials
