+# MongoDB 操作工具包
+用于操作MongoDB，简化开发流程。要使用此工具包，你的MongoDB**必须已经开启访问控制**。
+
+## 使用方法
+### 连接数据库
+
+```go
+var mongodb = am_mongo.MongoDB{
+	Host: "127.0..0.1",
+	Port: "27017",
+	Username: "root",
+	Password: "1234567"
+}
+
+err := mongodb.Connect("testdb")
+
+defer am_mongo.Close()
+```
+
+### 创建Model和唯一索引
+```go
+type User struct {
+	Name  string `bson:"name"`
+	Age   int    `bson:"age"`
+	Email string `bson:"email"`
+}
+
+mongodb.CreateUniqueIndex("testCollection", "email")
+```
+
+### CRUD
+#### 插入
+```go
+var user = User{
+	Name: "Joe Biden",
+	Age: 82,
+	Email: "heyjoebiden@gmail.com"
+}
+err := mongodb.Insert("testCollection", &user)
+```
+
+#### 查询
+```go
+// 条件查询
+var filter = bson.M{"email": "heyjowbiden@gmail.com"}
+var results []User
+
+err := mongodb.Find("testCollection", filter, &results)
+
+// 全数查询
+err = mongodb.Find("testCollection", bson.M{}, &results)
+```
+
+#### 修改
+```go
+var filter = bson.M{"email": "heyjowbiden@gmail.com"}
+var update = bson.M{"name": "Donald J Trump"}
+err := mongodb.Update("testCollection", filter, update)
+```
+
+#### 删除
+```go
+var filter = bson.M{"email": "heyjowbiden@gmail.com"}
+err := mongodb.Delete(filter)
+```
