+**Note:**
+Be aware that `git checkout` deliberately resets file modification dates (`mtime`).&nbsp;
+If you use GitHub Actions to publish your website, you'll need to restore file modification dates with a script or tool.
+One tool that does this is [chetan/git-restore-mtime-action](https://github.com/marketplace/actions/git-restore-mtime):
+```yaml
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          ref: main       #fetch the full git history of the "main"
+          fetch-depth: 0  #branch for git-restore-mtime-action
+      - uses: chetan/git-restore-mtime-action@v2
+      - uses: actions/setup-node@v4
+```
+For a working example, see: [publish-website.yaml](https://github.com/center-key/think-metric/blob/main/.github/workflows/publish-website.yaml)
 
 ## C) Application Code
