-# egg ORM plugin
+# egg-orm
+
+[中文介绍](Readme.zh-CN.md)
+
+Yet another object-relational mapping plugin for Egg, which is based on [Leoric](https://leoric.js.org).
+
+## Install
+
+```bash
+$ npm i --save egg-orm
+$ npm install --save mysql2   # MySQL or compatible dialects
+
+# Or use other database backend.
+$ npm install --save pg       # PostgreSQL
+$ npm install --save sqlite3  # SQLite
+```
+
+## Usage
+
+With egg-orm you can define models in `app/model`:
+
+```js
+// app/model/user.js
+module.exports = function(app) {
+  const { STRING } = app.model.DataTypes;
+
+  return app.model.define('User', {
+    name: STRING,
+    password: STRING,
+    avatar: STRING(2048),
+  }, {
+    tableName: 'users',
+  });
+}
+```
+
+and use them like below:
+
+```js
+// app/controller/home.js
+const { Controller } = require('egg');
+module.exports = class HomeController extends Controller {
+  async index() {
+    const users = await ctx.model.User.find({
+      corpId: ctx.model.Corp.findOne({ name: 'tyrael' }),
+    });
+    ctx.body = users;
+  }
+};
+```
+
+## Configuration
+
+Firstly, enable egg-orm plugin:
+
+```js
+// config/plugin.js
+exports.orm = {
+  enable: true,
+  package: 'egg-orm',
+};
+```
+
+Secondly, configure the plugin accordingly:
+
+```js
+// config/config.default.js
+exports.orm = {
+  client: 'mysql',
+  database: 'temp',
+  host: 'localhost',
+  baseDir: 'app/model',
+};
+```
+
+In this example above, we're accessing the `temp` database of MySQL via `localhost` with the models defined in directory `app/model`. For more information, please refer to [Setup Leoric in Egg](https://leoric.js.org/setup/egg).

+# egg-orm
+
+egg-orm 是一个适用于 Egg 框架的数据模型层插件，egg-orm 的对象关系映射能力来自 [Leoric](https://leoric.js.org)。
+
+## 安装
+
+```bash
+$ npm i --save egg-orm
+$ npm install --save mysql2   # MySQL 或者其他兼容 MySQL 的数据库
+
+# 其他数据库类型
+$ npm install --save pg       # PostgreSQL
+$ npm install --save sqlite3  # SQLite
+```
+
+## 使用
+
+开启 egg-orm 插件即可在 `app/model` 中定义数据模型：
+
+```js
+// app/model/user.js
+module.exports = function(app) {
+  const { STRING } = app.model.DataTypes;
+
+  return app.model.define('User', {
+    name: STRING,
+    password: STRING,
+    avatar: STRING(2048),
+  }, {
+    tableName: 'users',
+  });
+}
+```
+
+在 Controller 调用：
+
+```js
+// app/controller/home.js
+const { Controller } = require('egg');
+module.exports = class HomeController extends Controller {
+  async index() {
+    const users = await ctx.model.User.find({
+      corpId: ctx.model.Corp.findOne({ name: 'tyrael' }),
+    });
+    ctx.body = users;
+  }
+};
+```
+
+## 配置
+
+首先开启（并安装） egg-orm 插件
+
+```js
+// config/plugin.js
+exports.orm = {
+  enable: true,
+  package: 'egg-orm',
+};
+```
+
+然后按需配置数据库：
+
+```js
+// config/config.default.js
+exports.orm = {
+  client: 'mysql',
+  database: 'temp',
+  host: 'localhost',
+  baseDir: 'app/model',
+};
+```
+
+在上面这个例子中，我们将数据模型定义文件放在 `app/model` 目录，通过 `localhost` 访问 MySQL 中的 `temp` 数据库。推荐阅读 [在 Egg 中使用 Leoric](https://leoric.js.org/setup/egg)一文了解更多有关在 Egg 中使用 egg-orm 和 Leoric 的信息。
