+# beego orm
 
 a powerful orm framework
 
 now, beta, unstable, may be changing some api make your app build failed.
 
+**Driver Support:**
+
+* MySQL: [github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql)
+
+**Features:**
+
+...
+
+**Install:**
+
+	go get github.com/astaxie/beego/orm
+
+## Quick Start
+
+#### Simple Usage
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/astaxie/beego/orm"
+	_ "github.com/go-sql-driver/mysql" // import your used driver
+)
+
+// Model Struct
+type User struct {
+	Id   int    `orm:"auto"`
+	Name string `orm:"size(100)"`
+	orm.Manager
+}
+
+func init() {
+	// register model
+	orm.RegisterModel(new(User))
+
+	// set default database
+	orm.RegisterDataBase("default", "mysql", "root:root@/my_db?charset=utf8", 30)
+}
+
+func main() {
+	o := orm.NewOrm()
+
+	user := User{Name: "slene"}
+
+	// insert
+	id, err := o.Insert(&user)
+
+	// update
+	user.Name = "astaxie"
+	num, err := o.Update(&user)
+
+	// read one
+	u := User{Id: user.Id}
+	err = o.Read(&u)
+
+	// delete
+	num, err = o.Delete(&u)	
+}
+```
+
+#### Next with relation
+
+```go
+type Post struct {
+	Id    int    `orm:"auto"`
+	Title string `orm:"size(100)"`
+	User  *User  `orm:"rel(fk)"`
+	orm.Manager
+}
+
+var posts []*Post
+qs := o.QueryTable("post")
+num, err := qs.Filter("User__Name", "slene").All(&posts)
+```
+
+#### Use Raw sql
+
+```go
+var maps []Params
+num, err := o.Raw("SELECT id FROM user WHERE name = ?", "slene").Values(&maps)
+if num > 0 {
+	fmt.Println(maps[0]["id"])
+}
+```
+
+#### Transaction
+
+```go
+o.Begin()
+...
+user := User{Name: "slene"}
+id, err := o.Insert(&user)
+if err != nil {
+	o.Commit()
+} else {
+	o.Rollback()
+}
+
+```
