+
+          It looks like you are trying to merge a hotfix PR into `main`. If this isn't what you wanted to do, and you just wanted to make a regular PR, please close this PR, base your changes off the `devnet-ready` branch and open a new PR into `devnet ready`.
+
+          If you _are_ trying to merge a hotfix PR, please complete the following essential steps:
+          1. [ ] go ahead and get this PR into `main` merged, so we can get the change in as quickly as possible!
+          2. [ ] merge `main` into `testnet`, bumping `spec_version`
+          3. [ ] deploy `testnet`
+          4. [ ] merge `testnet` into `devnet`, bumping `spec_version`
+          5. [ ] deploy `devnet`
+          6. [ ] merge `devnet` into `devnet-ready`
+
+
+          If you do not complete these steps, your hotfix may be inadvertently removed in the future when branches are promoted to \`main\`, so it is essential that you do so.
