+        This form is **only** for issues in the **v6 beta**, which you
+        can access using either the `v6-beta` tag in the repository or
+        install using `ethers@beta` with `npm`.
+
+        The v6 branch will be very lively, undergoing a lot of changes,
+        including backwards compatible changes between beta versions.
+
+        Before opening an issue, please make sure you have
+        **fully updated to the latest version** by removing the
+        `node_modules/` and `package-lock.json` and then running a
+        fresh `npm install`. Otherwise you may end up with incompatible
+        versions which may conflict with each other.
+
+        Thanks for trying out the v6 beta! Cheers!
