+## Upgrading the Academy Theme
+
+The Layer5 Academy uses a maintained Hugo theme called [`academy-theme`](https://github.com/layer5io/academy-theme). As improvements are made to the theme, it is important to keep your local copy up to date to benefit from the latest features and fixes.
+
+To upgrade to the latest theme version, run: 
+```bash
+make theme-upgrade
+```
+
+This will trigger a sequence that updates the theme dependencies and applies the latest modules:
+```bash 
+hugo mod get -u
+hugo: collected modules in 1707 ms
+go: downloading github.com/layer5io/academy-theme v0.1.6
+go: upgraded github.com/layer5io/academy-theme v0.1.5 => v0.1.6
+go: upgraded github.com/twbs/bootstrap v5.3.6+incompatible => v5.3.7+incompatible
+```
+
+#### When should you upgrade the theme?
+
+- Before creating a release, to ensure you are using the most up-to-date theme.
+- If your preview or build seems outdated or missing recent design improvements.
+- After any update to the `academy-theme` repository is announced.
+> Run `hugo mod graph` to inspect which version of the theme you are currently using.
