+How to join a team / become a maintainer
+----------------------------------------
+
+Prospective maintainers are invited by other maintainers. As such, there is no way to apply to become one.
+
+That being said: we do have some tips for anyone striving to become a Godot maintainer:
+
+- **Take on maintainer tasks.** Many people assume that tasks like :ref:`reviewing PRs <doc_pr_review_guidelines>`,
+  taking on :ref:`team tasks <doc_triage_projects>` and critically :ref:`evaluating proposals <doc_evaluating_proposals>`
+  are reserved to maintainers. This is not true! These kinds of tasks are a major bottleneck for Godot's development,
+  so we appreciate everyone who contributes in this way.
+- **Be aligned with the project direction.** Try to work in the best interest of Godot.
+  Many people like implementing exciting new features, but often this is not the best way to contribute. What are other
+  ways to help? Where do you see problems or jobs that nobody else is taking on? What plans or roadblocks do the teams
+  currently have, and can you help? By being well informed and aligning with the teams, you can make effective
+  contributions in the interest of Godot.
+- **Earn trust from other maintainers.** Casual contributors come and go, but we take note of those who stay around
+  and communicate well, take on tasks and responsibility in an area, and are pro-active when solving problems and fixing
+  regressions.
