+# GORM MySQL Driver
+
+## Quick Start
+
+```go
+import (
+  "gorm.io/driver/mysql"
+  "gorm.io/gorm"
+)
+
+// https://github.com/go-sql-driver/mysql
+dsn := "gorm:gorm@tcp(localhost:9910)/gorm?charset=utf8&parseTime=True&loc=Local"
+db, err := gorm.Open(mysql.Open(dsn), &gorm.Config{})
+```
+
+## Configuration
+
+```go
+import (
+  "gorm.io/driver/mysql"
+  "gorm.io/gorm"
+)
+
+var datetimePrecision = 2
+
+db, err := gorm.Open(mysql.New(mysql.Config{
+  DSN: "gorm:gorm@tcp(localhost:9910)/gorm?charset=utf8&parseTime=True&loc=Local", // data source name, refer https://github.com/go-sql-driver/mysql#dsn-data-source-name
+  DefaultStringSize: 256, // add default size for string fields, by default, will use db type `longtext` for fields without size, not a primary key, no index defined and don't have default values
+  DisableDatetimePrecision: true, // disable datetime precision support, which not supported before MySQL 5.6
+  DefaultDatetimePrecision: &datetimePrecision, // default datetime precision
+  DontSupportRenameIndex: true, // drop & create index when rename index, rename index not supported before MySQL 5.7, MariaDB
+  DontSupportRenameColumn: true, // use change when rename column, rename rename not supported before MySQL 8, MariaDB
+  SkipInitializeWithVersion: false, // smart configure based on used version
+}), &gorm.Config{})
+```
+
+## Customized Driver
+
+```go
+import (
+  _ "example.com/my_mysql_driver"
+  "gorm.io/gorm"
+  "gorm.io/driver/mysql"
+)
+
+db, err := gorm.Open(mysql.New(mysql.Config{
+  DriverName: "my_mysql_driver_name",
+  DSN: "gorm:gorm@tcp(localhost:9910)/gorm?charset=utf8&parseTime=True&loc=Local", // data source name, refer https://github.com/go-sql-driver/mysql#dsn-data-source-name
+})
+```
