 # Go MYSQL Dump
 Create MYSQL dumps in Go without the `mysqldump` CLI as a dependancy.
 
+### Simple Example
+```go
+package main
+
+import (
+	"database/sql"
+	"fmt"
+
+	"github.com/JamesStewy/go-mysqldump"
+	_ "github.com/go-sql-driver/mysql"
+)
+
+func main() {
+	// Open connection to database
+  username := "your-user"
+  password := "your-pw"
+  hostname := "your-hostname"
+  port := "your-port"
+	dbname := "your-db"
+
+  dumpDir := "dumps"  // you should create this directory
+  dumpFilenameFormat := fmt.Sprintf("%s-20060102T150405", dbname)   // accepts time layout string and add .sql at the end of file
+
+	db, err := sql.Open("mysql", fmt.Sprintf("%s:%s@tcp(%s:%s)/%s", username, password, hostname, port, dbname))
+	if err != nil {
+		fmt.Println("Error opening database: ", err)
+		return
+	}
+
+	// Register database with mysqldump
+	dumper, err := mysqldump.Register(db, dumpDir, dumpFilenameFormat)
+	if err != nil {
+		fmt.Println("Error registering databse:", err)
+		return
+	}
+
+	// Dump database to file
+	resultFilename, err := dumper.Dump()
+	if err != nil {
+		fmt.Println("Error dumping:", err)
+		return
+	}
+	fmt.Printf("File is saved to %s", resultFilename)
+
+	// Close dumper and connected database
+	dumper.Close()
+}
+
+```
