+### Run a separate file with an async function

+You can also use async functions in this manner, as long as you `await` it in
+the inline script.
+
+In your workflow:
+
+```yaml
+on: push
+
+jobs:
+  echo-input:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - uses: actions/github-script@v3
+        env:
+          SHA: "${{env.parentSHA}}"
+        with:

+            const script = require(`${process.env.GITHUB_WORKSPACE}/path/to/script.js`)
+            await script({github, context, core})
+```
+
+And then export an async function from your module:
+
+```javascript
+module.exports = async ({ github, context, core }) => {
+    const { SHA } = process.env
+    const commit = await github.repos.getCommit({
+        owner: context.repo.owner,

+}

 ### Use npm packages
 
 Like importing your own files above, you can also use installed modules:
