+

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# Create a JavaScript Action using TypeScript
+
+Use this template to bootstrap the creation of a JavaScript action.:rocket:
+
+This template includes compilication support, tests, a validation workflow, publishing, and versioning guidance.  
+
+If you are new, there's also a simpler introduction.  See the [Hello World JavaScript Action](https://github.com/actions/hello-world-javascript-action)
+
+## Create an action from this template
+
+Click the `Use this Template` and provide the new repo details for your action
+
+## Code in Master
+
+Install the dependencies  
+```bash
+$ npm install
+```
+
+Build the typescript
+```bash
+$ npm run build
+```
+
+Run the tests :heavy_check_mark:  
+```bash
+$ npm test
+
+ PASS  ./index.test.js
+  ✓ throws invalid number (3ms)
+  ✓ wait 500 ms (504ms)
+  ✓ test runs (95ms)
+
+...
+```
+
+## Change action.yml
+
+The action.yml contains defines the inputs and output for your action.
+
+Update the action.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
+import * as core from '@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.
+
+## Publish to a distribution branch
+
+Actions are run from GitHub repos.  We will create a releases branch and only checkin production modules (core in this case). 
+
+Comment out node_modules in .gitignore and create a releases/v1 branch
+```bash
+# comment out in distribution branches
+# node_modules/
+```
+
+```bash
+$ git checkout -b releases/v1
+$ git commit -a -m "prod dependencies"
+```
+
+```bash
+$ npm prune --production
+$ git add node_modules
+$ git commit -a -m "prod dependencies"
+$ git push origin releases/v1
+```
+
+Your action is now published! :rocket: 
+
+See the [versioning documentation](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md)
+
+## Validate
+
+You can now validate the action by referencing the releases/v1 branch
+
+```yaml
+uses: actions/typescript-action@releases/v1
+with:
+  milliseconds: 1000
+```
+
+See the [actions tab](https://github.com/actions/javascript-action/actions) for runs of this action! :rocket:
+
+## Usage:
+
+After testing you can [create a v1 tag](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md) to reference the stable and tested action
+
+```yaml
+uses: actions/typescript-action@v1
+with:
+  milliseconds: 1000
+```
