+Getting Started
+---------------
+
+New contributors are very welcome and needed.
+
+Reviewing and testing is the most effective way you can contribute as a new
+contributor, and it also will teach you much more about the code and process
+than opening PRs. Please refer to the section [peer review](#peer-review) later
+in this document.
+
+Before you start contributing, familiarize yourself with the Dash Core build
+system and tests. Refer to the documentation in the repository on how to build
+Dash Core and how to run the unit and functional tests.
+
+There are many open issues of varying difficulty waiting to be fixed.
 If you're looking for somewhere to start contributing, check out the
