+# Quick Start
+
+## Create Engine
+
+```Go
+engine, err := xorm.NewEngine(driverName, dataSourceName)
+```
+
+## Define a struct and Sync2 table struct to database
+
+```Go
+type User struct {
+    Id int64
+    Name string
+    Salt string
+    Age int
+    Passwd string `xorm:"varchar(200)"`
+    Created time.Time `xorm:"created"`
+    Updated time.Time `xorm:"updated"`
+}
+
+err := engine.Sync2(new(User))
+```
+
+## Query a SQL string, the returned results is []map[string][]byte
+
+```Go
+results, err := engine.Query("select * from user")
+```
+
+## Execute a SQL string, the returned results
+
+```Go
+affected, err := engine.Exec("update user set age = ? where name = ?", age, name)
+```
+
+## Insert one or multipe records to database
+
+```Go
+affected, err := engine.Insert(&user)
+// INSERT INTO struct () values ()
+affected, err := engine.Insert(&user1, &user2)
+// INSERT INTO struct1 () values ()
+// INSERT INTO struct2 () values ()

+// INSERT INTO struct () values (),(),()
+affected, err := engine.Insert(&user1, &users)
+// INSERT INTO struct1 () values ()
+// INSERT INTO struct2 () values (),(),()
+```
+
+## Query one record from database
+
+```Go
+has, err := engine.Get(&user)
+// SELECT * FROM user LIMIT 1
+has, err := engine.Where("name = ?", name).Desc("id").Get(&user)
+// SELECT * FROM user WHERE name = ? ORDER BY id DESC LIMIT 1
+```
+
+## Query multiple records from database, also you can use join and extends
+
+```Go
+    var users []User
+    err := engine.Where("name = ?", name).And("age > 10").Limit(10, 0).Find(&users)
+    // SELECT * FROM user WHERE name = ? AND age > 10 limit 0 offset 10

+        Find(&users)
+    // SELECT user.*, detail.* FROM user INNER JOIN detail WHERE user.name = ? limit 0 offset 10
+```
+
+## Query multiple records and record by record handle, there two methods Iterate and Rows
+
+```Go
+err := engine.Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
+    user := bean.(*User)
+    return nil
+})
+// SELECT * FROM user

+// SELECT * FROM user
+defer rows.Close()
+bean := new(Struct)
+for rows.Next() {
+    err = rows.Scan(bean)
+}
+```
+
+## Update one or more records, default will update non-empty and non-zero fields except to use Cols, AllCols and etc.
+
+```Go
+affected, err := engine.Id(1).Update(&user)
+// UPDATE user SET ... Where id = ?
+
+affected, err := engine.Update(&user, &User{Name:name})
+// UPDATE user SET ... Where name = ?
+
+var ids = []int64{1, 2, 3}
+affected, err := engine.In(ids).Update(&user)
+// UPDATE user SET ... Where id IN (?, ?, ?)
+
+// force update indicated columns by Cols
+affected, err := engine.Id(1).Cols("age").Update(&User{Name:name, Age: 12})
+// UPDATE user SET age = ?, updated=? Where id = ?
+
+// force NOT update indicated columns by Omit
+affected, err := engine.Id(1).Omit("name").Update(&User{Name:name, Age: 12})
+// UPDATE user SET age = ?, updated=? Where id = ?
+
+affected, err := engine.Id(1).AllCols().Update(&user)
+// UPDATE user SET name=?,age=?,salt=?,passwd=?,updated=? Where id = ?
+```
+
+## Delete one or more records, Delete MUST has conditon
+
+```Go
+affected, err := engine.Where(...).Delete(&user)
+// DELETE FROM user Where ...
+```
+
+## Count records
+
+```Go
+counts, err := engine.Count(&user)

+# 快速开始
 
-## 案例
+## 第一步创建引擎，driverName, dataSourceName和database/sql接口相同
+
+```Go
+engine, err := xorm.NewEngine(driverName, dataSourceName)
+```
+
+## 定义一个和表同步的结构体，并且自动同步结构体到数据库
+
+```Go
+type User struct {
+    Id int64
+    Name string
+    Salt string
+    Age int
+    Passwd string `xorm:"varchar(200)"`
+    Created time.Time `xorm:"created"`
+    Updated time.Time `xorm:"updated"`
+}
+
+err := engine.Sync2(new(User))
+```
+
+## 最原始的也支持SQL语句查询，返回的结果类型为 []map[string][]byte
+
+```Go
+results, err := engine.Query("select * from user")
+```
+
+## 执行一个SQL语句
+
+```Go
+affected, err := engine.Exec("update user set age = ? where name = ?", age, name)
+```
+
+## 插入一条或者多条记录
+
+```Go
+affected, err := engine.Insert(&user)
+// INSERT INTO struct () values ()
+affected, err := engine.Insert(&user1, &user2)
+// INSERT INTO struct1 () values ()
+// INSERT INTO struct2 () values ()

+// INSERT INTO struct () values (),(),()
+affected, err := engine.Insert(&user1, &users)
+// INSERT INTO struct1 () values ()
+// INSERT INTO struct2 () values (),(),()
+```
+
+## 查询单条记录
+
+```Go
+has, err := engine.Get(&user)
+// SELECT * FROM user LIMIT 1
+has, err := engine.Where("name = ?", name).Desc("id").Get(&user)
+// SELECT * FROM user WHERE name = ? ORDER BY id DESC LIMIT 1
+```
+
+## 查询多条记录，当然可以使用Join和extends来组合使用
+
+```Go
+    var users []User
+    err := engine.Where("name = ?", name).And("age > 10").Limit(10, 0).Find(&users)
+    // SELECT * FROM user WHERE name = ? AND age > 10 limit 0 offset 10
+
+    type Detail struct {
+        Id int64
+        UserId int64 `xorm:"index"`
+    }
+
+    type UserDetail struct {
+        User `xorm:"extends"`
+        Detail `xorm:"extends"`
+    }
+
+    var users []UserDetail
+    err := engine.Table("user").Select("user.*, detail.*")
+        Join("INNER", "detail", "detail.user_id = user.id").
+        Where("user.name = ?", name).Limit(10, 0).
+        Find(&users)
+    // SELECT user.*, detail.* FROM user INNER JOIN detail WHERE user.name = ? limit 0 offset 10
+```
+
+## 根据条件遍历数据库，可以有两种方式: Iterate and Rows
+
+```Go
+err := engine.Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
+    user := bean.(*User)
+    return nil
+})
+// SELECT * FROM user
+
+rows, err := engine.Rows(&User{Name:name})
+// SELECT * FROM user
+defer rows.Close()
+bean := new(Struct)
+for rows.Next() {
+    err = rows.Scan(bean)
+}
+```
+
+## 更新数据，除非使用Cols,AllCols函数指明，默认只更新非空和非0的字段
+
+```Go
+affected, err := engine.Id(1).Update(&user)
+// UPDATE user SET ... Where id = ?
+
+affected, err := engine.Update(&user, &User{Name:name})
+// UPDATE user SET ... Where name = ?
+
+var ids = []int64{1, 2, 3}
+affected, err := engine.In(ids).Update(&user)
+// UPDATE user SET ... Where id IN (?, ?, ?)
+
+// force update indicated columns by Cols
+affected, err := engine.Id(1).Cols("age").Update(&User{Name:name, Age: 12})
+// UPDATE user SET age = ?, updated=? Where id = ?
+
+// force NOT update indicated columns by Omit
+affected, err := engine.Id(1).Omit("name").Update(&User{Name:name, Age: 12})
+// UPDATE user SET age = ?, updated=? Where id = ?
+
+affected, err := engine.Id(1).AllCols().Update(&user)
+// UPDATE user SET name=?,age=?,salt=?,passwd=?,updated=? Where id = ?
+```
+
+## 删除记录，需要注意，删除必须至少有一个条件，否则会报错。要清空数据库可以用EmptyTable
+
+```Go
+affected, err := engine.Where(...).Delete(&user)
+// DELETE FROM user Where ...
+```
+
+## 获取记录条数
+
+```Go
+counts, err := engine.Count(&user)
+// SELECT count(*) AS total FROM user
+```
