+## Ideas for beginners
+
+If you're not an experienced C++ programmer, you can still help Kea in many ways. To help newcomers get
+involved in the project, we try to mark easy tickets with `beginner` label. Examples of such tasks may be
+elimination of compilation warnings, adding or fixing logging messages, improving the build
+system to not leave unnecessary files, conduct some experiments and improve documentation. You can see the
+list of all tickets with that label here:
+https://gitlab.isc.org/isc-projects/kea/-/issues?scope=all&utf8=%E2%9C%93&state=opened&label_name[]=beginner
+
+Don't be discouraged if a ticket that looks interesting to you is not marked for beginners. It may require
+a bit of DHCP protocol or C++ programming knowledge, but they're definitely all doable. If in doubt, ask on
+kea-dev list for suggestions or guidance.
