+
+Try to reproduce it using the current `libsodium-stable` package, downloaded from [the official download site](https://download.libsodium.org/libsodium/releases/), and installed [as documented](https://doc.libsodium.org/installation).
+
+If you don't have any clear understanding of the issue or can't enumerate the steps to reproduce it, open a discussion instead: https://github.com/jedisct1/libsodium/discussions

+Please do not post features requests directly.
+
+The starting point should be a discussion, after having checked the [roadmap](https://doc.libsodium.org/roadmap).
+
+Suggestions should be raised as an "Ideas" [discussion](https://github.com/jedisct1/libsodium/discussions/).
+
+We can then determine if the discussion needs to be escalated into a "planned change" or not.
+
+This will help us ensure that the issue tracker properly reflects ongoing or needed work on the project.

+Thank you! 😊🙏
