 ### Important note about automated GitHub checks
 
-When you submit a pull request, GitHub automatically runs checks on the Minetest Engine combined with your changes. One of these checks is called 'cpp lint / clang format', which checks code formatting. Because formatting for readability requires human judgement this check often fails and often makes unsuitable formatting requests which make code readability worse.

-If this check fails, look at the details to check for any clear mistakes and correct those. However, you should not apply everything ClangFormat requests. Ignore requests that make code readability worse and any other clearly unsuitable requests. Discuss in the pull request with a core developer about how to progress.

+
+If a Pull Request is not a bug fix:
+
+* If it matches a goal in [the roadmap](../doc/direction.md), then the PR should
+  be labelled as "Roadmap" and the goal stated by number in the description.
+* If it doesn't match a goal, then it needs to receive a concept approval within
+  a week of being opened to remain open. This 1 week deadline does not apply to
+  PRs opened before the roadmap was adopted; instead, they may remain open or be
+  closed as needed. Use the "Concept Approved" label. Issues can be marked as
+  "Concept Approved" to give preapproval to future PRs.
