 ## Usage
 
-Core customization occurs in `_config.yml`. Aside from the usual configuration variables, you can set a value for the variable `home`, which specifies the page of your site to which you want the home button in the navigation bar to redirect.

If no value is provided for this variable, the whole copyright notice is suppressed (this is the default). Finally, you can set a value for `indexing`, which tells search engine crawlers whether to index your site. The default value is `false`, and in this case the following code is included in the head of every page:
 
 ```html
-<meta name="robots" content="noindex, nofollow">
+<meta name="robots" content="none">
 ```
 
-If you set `indexing: true`, however, crawlers will be allowed to index your site and Jekyll will populate the head of every page with SEO tags through the `jekyll-seo-tag` plugin.

 Data that appears in the theme's four default pages must be configured via YAML files located in the `_data` folder. See the corresponding files in `demo/_data` to understand how to write your own YAML, or better yet, clone these files and edit them.
