+
+> Action for zipping files easily
+
+## Usage
+
+The only requirement is to use the official `actions/checkout@v2` first so the zip action has access to the repo files.
+
+```yaml
+name: Zip Files
+
+on:
+  release:
+    types: [published]
+
+jobs:
+  zip-files:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - uses: papeloto/action-zip@v1
+        with:
+          files: dist/ manifest.json
+          dest: result.zip
+```
+
+In this example, after a release is published, a new file named `result.zip` will be created with both the file `manifest.json` and the folder `dist` (files included).
+
