-Use this template to bootstrap the creation of a JavaScript action.:rocket:
+This action sets up [Alibaba Cloud OSSUTIL](https://github.com/aliyun/ossutil) for use in actions by:
 
-This template includes compilication support, tests, a validation workflow, publishing, and versioning guidance.  
+- downloading and caching ossutil by version and adding to PATH
+- configuring ossutil with your credentials
 
-If you are new, there's also a simpler introduction.  See the [Hello World JavaScript Action](https://github.com/actions/hello-world-javascript-action)
+## Usage
 
-## 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

-```
-
-## 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
+See [action.yml](action.yml)
