+## Version Support Policy
+As our project is maintained by a small team, we must focus our limited resources on following upstream projects and ensuring the stability of the latest version.
+
+Consequently, **we do not provide bug fixes or security patches for older versions.** Our official support is limited to **the latest version of the upstream projects** only.
+
+We strongly encourage all users to upgrade to the latest version to benefit from the most recent features, bug fixes, and security patches.
+
+### For Users Unable to Upgrade
+> **Warning:**
+> This doesn't work all the time. We strongly recommend upgrading Helm Chart to the latest version.
+
+If you are unable to upgrade to the latest version due to specific constraints, please follow the below to patch.
+
+1. Upgrade Helm Chart to the latest version for your minor version. e.g: If you used `v8.2.0`, update to `v8.2.6`, the latest version of `v8.2.x`.
+2. Override the image tag (`.global.image.tag`) to use a specific version.
+
+### How You Can Help
+This policy may evolve as our team grows. If you are interested in joining our team and helping us expand our support capabilities, we encourage you to read the [Community Membership Guide](https://github.com/argoproj/argoproj/blob/main/community/membership.md) for details.
