In this repository I add some tips, tricks and describe how you add features to your Wordpress. You might want to add some features to your functions.php file or manipulate files from plug-ins.
I found out that Yoast SEO premium was not built with custom post types in mind.

When you integrate custom post types, they won't show up in your search results by default. The content of this page will help you to add your custom post types to the search corpus.
