clarity is a MathJax ready Pure based theme for Ghost.
It is already integrated with microdata for search engine optimization and opengraph for better facebook integration.
You can see a running version of the dark theme is on my blog Tales of a Fractal Spectrum.
Please note that this new version integrates some changes of Ghost 1.6.* and will not work on older installations. Consider upgrading Ghost to version 1.6.0 before upgrading the theme!
The zip contains the full theme with a detailed README.
It is ready to be integrated with your favorite social networks, ready to be used with google+, disqus or Facebook comments and ready to be integrated with Google Analytics. Until this will be made automatic with the introduction of plugins in Ghost, you will find detailed instructions on the README file.
For some of the following operations you need to edit css or hbs files. Use your favourite pure text editor for the purpose. Please avoid Office, LibreOffice/OpenOffice or similar suites.
Decompress the zip file inside the folder content/themes/ of your Ghost blog.
Or, go into Design on your http://yourblog.com/ghost/ and load in the zip file.
Open the file default.hbs and look for the following lines
<ul class="social-list">
<a href="https://www.github.com/.../" target="_blank"><i class="fa fa-github-alt" aria-hidden="true"></i></a>
<a href="https://www.linkedin.com/in/.../" target="_blank"><i class="fa fa-linkedin" aria-hidden="true"></i></a>

</ul>
The fa fa-SocialNetworkName identifies which icon is used and more details can be found by visiting http://fontawesome.io/
Duplicating those line and editing the name of the icon and the link will add additional social networks. For the full list of supported icons, please refer to the font awesome website.
To enable MathJax (if you don't know it, probably you don't need it) it is enough to open the file default.hbs and completely delete the two lines containing the text REMOVE THIS LINE TO ENABLE MATHJAX.
After having obtained your Account Code from analytics.google.com, it is a code of the form UA-12345678-1, open the file default.hbs, completely delete the two lines containing the text REMOVE THIS LINE TO ENABLE GOOGLE ANALYTICS and replace REPLACE_THIS_TEXT_WITH_THE_ACCOUNT_NUMBER_GIVEN_BY_GOOGLE with your account code.
To set up google+, disqus or facebook comments is enough to open posts.hbs, and remove the appropriate lines at the end of the file (they are marked with REMOVE THIS LINE TO ENABLE ...).
For Disqus you additionally need to register to their website and obtain a website identifier.
You can add the Comments counter on the index page modifying the code according to Another way of enabling disqus on Ghost.
