 Create a Client:
 
 ```go
-	config := &Config{
-		Addresses: []*Address{
-			{
-				Host: "127.0.0.1",
-				Port: 8086,
-			},
+config := &Config{

-		fmt.Println(err)
-	}
+	},
+}
+client, err := NewClient(config)
+if err != nil {
+	fmt.Println(err)
+}
 ```
 
 Create a Database:
 
 ```go
-	exampleDatabase := "ExampleDatabase"
-	err = client.CreateDatabase(exampleDatabase)
-	if err != nil {
-		fmt.Println(err)
-		return
-	}
+exampleDatabase := "ExampleDatabase"

 Write single point:
 
 ```go
-	exampleMeasurement := "ExampleMeasurement"
-	point := &Point{}
-	point.SetMeasurement(exampleMeasurement)
-	point.AddTag("Weather", "foggy")
-	point.AddField("Humidity", 87)
-	point.AddField("Temperature", 25)
-	err = client.WritePoint(exampleDatabase, point, func(err error) {
-		if err != nil {
-			fmt.Printf("write point failed for %s", err)
-		}
-	})
+exampleMeasurement := "ExampleMeasurement"
+point := &Point{}
+point.SetMeasurement(exampleMeasurement)
+point.AddTag("Weather", "foggy")
+point.AddField("Humidity", 87)

-		fmt.Println(err)
+		fmt.Printf("write point failed for %s", err)
 	}
+})
+if err != nil {

 ```
 Write batch points:
 
 ```go
-	exampleMeasurement := "ExampleMeasurement"
-	bp := &BatchPoints{}
-	var tagList []string
-	tagList = append(tagList, "sunny", "rainy", "windy")
-	for i := 0; i < 10; i++ {

 Do a query:
 
 ```go
-	q := Query{
-		Database: exampleDatabase,
-		Command:  "select * from " + exampleMeasurement,
-	}
-	res, err := client.Query(q)
-	if err != nil {
-		fmt.Println(err)

-	for _, r := range res.Results {
-		for _, s := range r.Series {
-			for _, v := range s.Values {
-				for _, i := range v {
-					fmt.Print(i)
-					fmt.Print(" | ")
-				}
-				fmt.Println()
+q := Query{
+	Database: exampleDatabase,
+	Command:  "select * from " + exampleMeasurement,
+}
+res, err := client.Query(q)
+if err != nil {
+	fmt.Println(err)
+}
+for _, r := range res.Results {
+	for _, s := range r.Series {
+		for _, v := range s.Values {
+			for _, i := range v {
+				fmt.Print(i)
+				fmt.Print(" | ")
 			}
