 # @vue/cli-plugin-typescript
 
 > typescript plugin for vue-cli
+
+Uses TypeScript + `ts-loader` + [fork-ts-checker-webpack-plugin](https://github.com/Realytics/fork-ts-checker-webpack-plugin) for faster off-thread type checking.
+
+## Configuration
+
+TypeScript can be configured via `tsconfig.json`.
+
+This plugin can be used alongside `@vue/cli-plugin-babel`. When used with Babel, this plugin will output ES2015 and delegate the rest to Babel for auto polyfill based on browser targets.
+
+By default, `ts-loader` is only applied to files inside `src` and `test` directories. If you wish to explicitly transpile a dependency module, you will need to configure webpack in `vue.config.js`:
+
+``` js
+module.exports = {
+  chainWebpack: config => {
+    config
+      .rule('ts')
+        .include
+          .add(/module-to-transpile/)
+  }
+}
+```
+
+## Injected Commands
+
+If opted to use [TSLint](https://palantir.github.io/tslint/) during project creation, `vue-cli-service lint` will be injected.
+
+## Caching
+
+[cache-loader](https://github.com/webpack-contrib/cache-loader) is enabled by default and cache is stored in `<projectRoot>/node_modules/.cache/cache-loader`.
+
+## Parallelization
+
+[thread-loader](https://github.com/webpack-contrib/thread-loader) is enabled by default when the machine has more than 1 CPU cores. This can be turned off by setting `parallel: false` in `vue.config.js`.
+
+## Installing in an Already Created Project
