+
+*This feature is on beta.*
+*Any feedback is welcome at [Issue #163](https://github.com/peaceiris/actions-gh-pages/issues/163)*
+
+Set files or directories to exclude from publishing assets.
+The default is `.github`.
+Values should be split with a comma.
+
+```yaml
+- name: Deploy
+  uses: peaceiris/[email protected]
+  with:
+    github_token: ${{ secrets.GITHUB_TOKEN }}
+    exclude_assets: '.github,exclude-file1,exclude-file2'
+```
+
+Set `exclude_assets` to empty for including the `.github` directory to deployment assets.
+
+```yaml
+- name: Deploy
+  uses: peaceiris/[email protected]
+  with:
+    github_token: ${{ secrets.GITHUB_TOKEN }}
+    exclude_assets: ''
+```
+
+The `exclude_assets` option supports glob patterns.
+
+```yaml
+- name: Deploy
+  uses: peaceiris/[email protected]
+  with:
+    github_token: ${{ secrets.GITHUB_TOKEN }}
+    exclude_assets: '.github,exclude-file.txt,exclude-dir/**.txt'
