 ## QuickStart
 
 ### Development
-```shell
-$ npm install
-$ npm run tsc:w
+
+```bash
+$ npm i
 $ npm run dev
 $ open http://localhost:7001/
 ```
 
-### Deploy
+Don't tsc compile at development mode, if you had run `tsc` then you need to `npm run clean` before `npm run dev`.
 
-Use `EGG_SERVER_ENV=prod` to enable prod mode
+### Deploy
 
-```shell
-$ EGG_SERVER_ENV=prod npm start
+```bash
+$ npm run tsc
+$ npm start
 ```
 
 ### Npm Scripts
 
-- Use `npm run autod` to auto detect dependencies upgrade
 - Use `npm run lint` to check code style
 - Use `npm test` to run unit test
+- se `npm run clean` to clean compiled js at development mode once
 
 ### Requirement
 
-Please ensure your node version is `>=7.6.0` for async await support without flag. If your node version is `>=7.0.0 < 7.6.0`, you can run npm scripts with harmony flag
-
-```shell
-# start server
-npm run dev -- --harmony-async-await
-# run test cases
-npm run test-local -- --harmony-async-await
-```
+- Node.js 8.x
+- Typescript 2.8+
