+# Templates and Guides
+
+In this directory you will find templates and writing guides that you can use when contributing new documentation to the repo.
+
+## Why templates and guides?
+
+At ClickHouse we believe that high quality documentation is vitally important to our community as it helps them get the most
+out of ClickHouse quickly. We also recognise that documentation at ClickHouse is a collective effort, with a diverse range of 
+people contributing content, not all of whom are technical writers. Fortunately, you don't have to be one to still contribute
+great documentation. In this directory you'll find templates and guidelines for various types of content. We use these to help
+ensure that our documentation is consistent, and therefore more readable and maintainable, and also to assist you in writing 
+quality content for the documentation.
