+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 Bitcoin Core build
+system and tests. Refer to the documentation in the repository on how to build
+Bitcoin 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

+### Good First Issue Label
+
+The purpose of the `good first issue` label is to highlight which issues are
+suitable for a new contributor without a deep understanding of the codebase.
+
+However, good first issues can be solved by anyone. If they remain unsolved
+for a longer time, a frequent contributor might address them.
+
+You do not need to request permission to start working on an issue. However,
+you are encouraged to leave a comment if you are planning to work on it. This
+will help other contributors monitor which issues are actively being addressed
+and is also an effective way to request assistance if and when you need it.
