+Below is a list of the parameters that Beautiful Jekyll supports (any of these can be added to the YAML front matter of any page). Remember to also look in the `_config.yml` file to see additional site-wide settings. If there's a parameter that you want to apply to the entire site instead of one specific page, check out [this FAQ answer](https://beautifuljekyll.com/faq/#default-params).
## Main parameters
@@ -146,6 +146,7 @@ tags | List of tags to categorize the post. Separate the tags with commas
cover-img | Include a large full-width image at the top of the page. You can either provide the path to a single image (eg. `"/path/to/img"`) , or a list of images to cycle through (eg. `["/path/img1", "/path/img2"]`). If you want to add a caption to an image, then you must use the list notation (use `[]` even if you have only one image), and each image should be provided as `"/path/to/img" : "Caption of image"`.
thumbnail-img | For blog posts, if you want to add a thumbnail that will show up in the feed, use `thumbnail-img: /path/to/image`. If no thumbnail is provided, then `cover-img` will be used as the thumbnail. You can use `thumbnail-img: ""` to disable a thumbnail.
comments | If you want do add comments to a specific page, use `comments: true`. Comments only work if you enable one of the comments providers (Facebook, disqus, staticman, utterances, giscus, CommentBox) in `_config.yml` file. Comments are automatically enabled on blog posts but not on other pages; to turn comments off for a specific post, use `comments: false`.
+mathjax | If you want to use LaTeX formulas, you need to enable MathJax. Note that in MathJax you need to use `$$` and `\\(` to start and end expressions

- You can also check out the [advanced installation methods](https://beautifuljekyll.com/getstarted/#install-steps-hard) that give you a little more control but are harder to use. Keep in mind that Beautiful Jekyll was primarily designed to be used as a GitHub theme, so you will not get any support if you choose one of the Ruby installation methods.
