+
+To enable a color scheme, set the `color_scheme` parameter in your site's `_config.yml` file:

+
+
+## Specific visual customization
 
 To customize your site’s aesthetic, open `_sass/custom/custom.scss` in your editor to see if there is a variable that you can override. Most styles like fonts, colors, spacing, etc.. are derived from these variables. To override a specific variable, uncomment out it’s line and change it’s value.
 
-For example, to change the link color from the purple default to blue, open `_sass/custom/custom.css` and find the link color variable on line `44`. Uncomment it out, and change it's value to our `$blue-000` variable, or another shade of your choosing.
+For example, to change the link color from the purple default to blue, open `_sass/custom/custom.css` and find the `$link-color` variable on line `50`. Uncomment it out, and change it's value to our `$blue-000` variable, or another shade of your choosing.
