+# JavaScript Action Template
+
+A template to bootstrap the creation of a JavaScript action with tests, linting, a validation workflow and publishing scripts.
+
+## Create an action from this template
+
+Click the `Use this Template` and provide the new repo details for your action
+
+## Code in Master
+
+```bash
+$ npm install
+```
+
+```bash
+$ npm test
+
+ PASS  ./index.test.js
+  ✓ throws invalid number (3ms)
+  ✓ wait 500 ms (504ms)
+  ✓ test runs (95ms)
+
+...
+```
+
+## Change actions.yml
+
+The actions.yml contains defines the inputs and output for your action.
+
+Update the actions.yml with your name, description, inputs and outputs for your action.
+
+See the [documentation](https://help.github.com/en/articles/metadata-syntax-for-github-actions)
+
+## Change the Code
+
+Most toolkit and CI/CD operations involve async operations so the action is run in an async function.
+
+```javascript
+const core = require('@actions/core');
+...
+
+async function run() {
+  try { 
+      ...
+  } 
+  catch (error) {
+    core.setFailed(error.message);
+  }
+}
+
+run()
+```
+
+See the [toolkit documentation](https://github.com/actions/toolkit/blob/master/README.md#packages) for the various packages.
+
+## Usage:
+
+The uses path will be the org and repo where you create your action
+
+```yaml
+uses: actions/javascript-action@v1
+with:
+  milliseconds: 1000
+```
