+          ### Uses prettier https://prettier.io to format jekyll output HTML.
+          #
+          # prettier_opts: '{ "useTabs": true }'
+          ### Sets prettier options (in JSON) to format output HTML. For example, output tabs over spaces.
+          ### Possible options are outlined in https://prettier.io/docs/en/options.html
+          #
+          # prettier_ignore: 'about/*'
+          ### Ignore paths for prettier to not format those html files.
+          ### Useful if the file is exceptionally large, so formatting it takes a while.
+          ### Also useful if HTML compression is enabled for that file / formatting messes it up.

+          ### If the jekyll website source is not in root, specify the directory. (in this case, sample_site)

+          gem_src: docs
+          ### By default, this is not required as the action searches for a _config.yml automatically.
+          ### However, if there are multiple Gemfiles, the action may not be able to determine which to use.
+          ### In that case, specify the directory. (in this case, sample_site)
+          ###
+          ### If jekyll_src is set, the action would automatically choose the Gemfile in jekyll_src.
+          ### In that case this input may not be needed as well.

+          # custom_opts: '--drafts --lsi'
