Most of the `doc` pages are generated from [Jupyter notebooks](http://jupyter.org/) in the [notebooks](https://github.com/facebook/prophet/tree/main/notebooks) directory at the base of the source tree. Please make changes there and then rebuild the docs:
The requirements for running a GitHub pages site locally is described in [GitHub help](https://help.github.com/articles/setting-up-your-github-pages-site-locally-with-jekyll/#requirements). The steps below summarize these steps.
> If you have run the site before, you can start with step 1 and then move on to step 5.
1. Ensure that you are in the same directory where this `README.md` exists (e.g., it could be in `/docs` on `main`, in the root of a `gh-pages` branch, etc). The below RubyGems commands, etc must be run from there.
- For content changes only, you can use `--incremental` for faster builds.
```
bundle exec jekyll serve --incremental
```
> We use `bundle exec` instead of running straight `jekyll` because `bundle exec` will always use the version of Jekyll from our `Gemfile`. Just running `jekyll` will use the system version and may not necessarily be compatible.
- To run using an actual IP address, you can use `--host=0.0.0.0`
```
bundle exec jekyll serve --host=0.0.0.0
```
This will allow you to use the IP address associated with your machine in the URL. That way you could share it with other people.
e.g., on a Mac, you can your IP address with something like `ifconfig | grep "inet " | grep -v 127.0.0.1`.
1. Either of commands in the previous step will serve up the site on your local device at http://127.0.0.1:4000/ or http://localhost:4000.
### Updating the Bundle
The site depends on Github Pages and the installed bundle is based on the `github-pages` gem.
Occasionally that gem might get updated with new or changed functionality. If that is the case,
