 Settings that affect your entire site can be changed in [Jekyll's configuration file](https://jekyllrb.com/docs/configuration/): `_config.yml`, found in the root of your project. If you don't have this file you'll need to copy or create one using the theme's [default `_config.yml`](https://github.com/mmistakes/minimal-mistakes/blob/master/_config.yml) as a base.

 ###### Configure Staticman

+Default settings have been provided in `_config.yml`. The important ones to set are  `provider: "staticman"`, `branch`, and `path`. View the [full list of configurations](https://github.com/eduardoboucas/staticman#jekyll-configuration).
 
 **Branch setting:** This is the branch comment files will be sent to via pull requests. If you host your site on GitHub Pages it will likely be `master` unless your repo is setup as a project --- use `gh-pages` in that case.
