 For more extensive changes to Ploty's JavaScript documentation, we suggest getting the Jekyll application which builds the site to run locally so that you can test your changes as you develop them. 
 
-This involves cloning the repository and installing its dependencies: [Git](https://git-scm.com/), [Ruby]((https://www.ruby-lang.org/en/), [Jekyll](https://jekyllrb.com/), and the [Python `requests` package](https://pypi.org/project/requests/). 
 
 1. Use [`git`](https://git-scm.com/) to [clone](https://git-scm.com/docs/git-clone) the public `plotly/graphing-library-docs` repository.

+#### Reducing build times

 **Note** The default Jekyll configuration file only builds the JavaScript posts by [excluding folders](https://jekyllrb.com/docs/configuration/options/). If you want to override this behavior, serve the application with a custom Jekyll configuration file in the root of the repository. Do this by copying `_config_dev.yml`, renaming it `_config_personal.yml`, and modifying the `exclude` statement. 
 
 - If you name the Jekyll configuration file `_config_personal.yml`, it will be caught by the `.gitignore` file and not committed to version control.
