+      - When reporting bugs, you'll make our life simpler (and the fix will come sooner) if you follow the guidelines in this template.
+      - Write a descriptive issue title above.
+      - The golden rule is to **always open *one* issue for *one* bug**. If you notice several bugs and want to report them, make sure to create one new issue for each of them.
+      - Search [open](https://github.com/godotengine/godot-cpp/issues) and [closed](https://github.com/godotengine/godot-cpp/issues?q=is%3Aissue+is%3Aclosed) issues to ensure it has not already been reported. If you don't find a relevant match or if you're unsure, don't hesitate to **open a new issue**. The bugsquad will handle it from there if it's a duplicate.
+      - Verify that you are using a [supported Godot version](https://docs.godotengine.org/en/latest/about/release_policy.html).
