+
+[English Document](README.md)
+
+### 1.介绍
+
+mongo-dao-generator是一个自动化生成MongoDB数据访问对象（Data Access Object）的工具。
+
+### 2.优势
+
+* 支持primitive.ObjectID、primitive.DateTime类型的自动填充。
+
+* 支持int、int8、int16、int32、int64、uint、uint8、uint16、uint32、uint64类型的自增长。
+
+* 提供了对数据库字段的统一生成方案，避免了业务代码中随处可见的数据库字段的问题。
+
+* 提供了包括InsertOne、InsertMany、UpdateOne、UpdateOneByID、UpdateMany、FindOne、FindOneByID、FindMany、DeleteOne、DeleteOneByID、DeleteMany、Count、Aggregate等多种数据库操作接口。
+
+* 提供了对数据库操作接口的扩展能力。

+
+### 3.安装
+
+```shell
+go intall github.com/dobyte/mongo-dao-generator

+
+```shell
+Usage of mongo-dao-generator:

+```
+
+### 5.标签
+
+在模型定义中支持对gen标签的解析，目前支持以下标签解析：
+
+| 标签名称     |                                                            | 示例                 | 说明                         |
+| -------- | ---------------------------------------------------------- | ------------------ | -------------------------- |
+| autoFill | primitive.ObjectID、primitive.DateTime                      | gen:"autoFill"     |                            |
+| autoIncr | int、int8、int16、int32、int64、uint、uint8、uint16、uint32、uint64 | gen:"autoIncr:uid" | 该自增为原子操作，会在生成代码时同步生成计数器代码。 |
+
+### 6.示例
+
+###### 6-1.创建模型
+
+model/mail.go
+
+```go
+package model
+
+import "go.mongodb.org/mongo-driver/bson/primitive"
+
+//go:generate mongo-dao-generator -model-dir=. -model-names=Mail -dao-dir=../dao/
+type Mail struct {
+    ID       primitive.ObjectID `bson:"_id" gen:"autoFill"`       // 邮件ID
+    Title    string             `bson:"title"`                    // 邮件标题
+    Content  string             `bson:"content"`                  // 邮件内容
+    Sender   int64              `bson:"sender"`                   // 邮件发送者
+    Receiver int64              `bson:"receiver"`                 // 邮件接受者
+    Status   int                `bson:"status"`                   // 邮件状态
+    SendTime primitive.DateTime `bson:"send_time" gen:"autoFill"` // 发送时间
+}

+# mongo-dao-generator
+
+##### [中文文档](README-zh.md)
+
+### 1.Introduction
+
+mongo-dao-generator is a tool for automatically generating MongoDB Data Access Object.
+
+### 2.Advantage
+
+* Supports automatic filling of primitive.ObjectID and primitive.DateTime types.
+
+* Supports automatic increment of int, int8, int16, int32, int64, uint, uint8, uint16, uint32 and uint64 types.
+
+* Provides a unified generation scheme for database fields, avoiding the problem of database fields that can be seen everywhere in business codes.
+
+* Provides various database operation interfaces including InsertOne, InsertMany, UpdateOne, UpdateOneByID, UpdateMany, FindOne, FindOneByID, FindMany, DeleteOne, DeleteOneByID, DeleteMany, Count, Aggregate, etc.
+
+* Provides the ability to expand the database operation interface.
+
+* Provides two package solutions: subcontracting and non-subcontracting.
+
+* Supports customization of directory and file name styles.
+
+### 3.Download and install
+
+```shell
+go intall github.com/dobyte/mongo-dao-generator
+```
+
+### 4.Usage

+
+### 5.Extension tags
+
+The parsing of gen tags is supported in the model definition, and the following tag parsing is currently supported:
+
+| Tag Name |                                                            | Example            | Description                                                                                         |
+| -------- | ---------------------------------------------------------- | ------------------ | --------------------------------------------------------------------------------------------------- |
+| autoFill | primitive.ObjectID、primitive.DateTime                      | gen:"autoFill"     |                                                                                                     |
+| autoIncr | int、int8、int16、int32、int64、uint、uint8、uint16、uint32、uint64 | gen:"autoIncr:uid" | The increment is atomic and the counter code is generated synchronously when the code is generated. |
