+# Solo Release Checklist
+
+## 1. Verify Workflows
+- Check that the last merge to `main` passed all workflows:
+  - https://github.com/hiero-ledger/solo/actions?query=branch%3Amain
+
+## 2. Validate Documentation Site
+- Review deployed docs:
+  - https://solo.hiero.org/main/docs/advanced-deployments/
+- Check other key pages for correctness
+- Note: Site updates automatically on PR merge to `main`
+
+## 3. Compare Changes Since Last Release
+- Compare latest tag with `main`:
+  - Example:
+    - https://github.com/hiero-ledger/solo/compare/v0.63.0...main
+
+## 4. Determine Next Version
+- Review commit messages
+- Follow commit message conventions from PR template
+- Alternatively:
+  - Run release workflow with `dry-run` to determine version
+
+## 5. Review Migration Impact
+- Inspect changes in `/data` folder:
+  - Local config migrations
+  - Remote config migrations
+- Confirm migration scenarios are covered
+- Assess impact on:
+  - Helm chart upgrades
+- Decide version bump:
+  - Patch / Minor / Major
+
+## 6. Update Documentation (Skip if PATCH)
+- Create PR updating:
+  - `README.md`
+  - `docs/legacy-versions.md`
+- Include:
+  - New Solo version
+  - Helm chart version
+  - CN / Hedera versions
+  - Release date
+  - End of support:
+    - Odd versions → 1 month
+    - Even versions → 3 months
+- Get approval and merge PR
+
+## 7. Run Release Workflow
+- Workflow:
+  - https://github.com/hiero-ledger/solo/actions/workflows/flow-deploy-release-artifact.yaml
+- Settings:
+  - **Use workflow from:** `main`
+  - **Dual publish:** `true`
+  - **Dry run:** `false`
+
+## 8. Update npm `latest` Tag (Manual)
+> ⚠️ Requires npm access
+- npm dist-tag add @hashgraph/solo@<version> latest
+
+## 9. Verify npm Package (@hashgraph)
+- https://www.npmjs.com/package/@hashgraph/solo?activeTab=versions
+
+## 10. Verify JFrog Artifactory (@hashgraph)
+- https://artifacts.swirldslabs.io/ui/packages/npm:%2F%2F@hashgraph%2Fsolo/
