 This package uses structs, that contain the 'ovs' field tag to determine which field goes to
 which column in the database. We refer to pointers to this structs as Models. Example:
 
-   type MyLogicalSwitch struct {
-   	UUID   string            `ovsdb:"_uuid"` // _uuid tag is mandatory
-   	Name   string            `ovsdb:"name"`
-   	Ports  []string          `ovsdb:"ports"`
-   	Config map[string]string `ovsdb:"other_config"`
-   }
+	type MyLogicalSwitch struct {
+		UUID   string            `ovsdb:"_uuid"` // _uuid tag is mandatory
+		Name   string            `ovsdb:"name"`
+		Ports  []string          `ovsdb:"ports"`
+		Config map[string]string `ovsdb:"other_config"`
+	}
 
 Based on these Models a Database Model (see ClientDBModel type) is built to represent
 the entire OVSDB:
 
-   clientDBModel, _ := client.NewClientDBModel("OVN_Northbound",
-       map[string]client.Model{
-   	"Logical_Switch": &MyLogicalSwitch{},
-   })
-
+	clientDBModel, _ := client.NewClientDBModel("OVN_Northbound",
+	    map[string]client.Model{
+		"Logical_Switch": &MyLogicalSwitch{},
+	})
 
 The ClientDBModel represents the entire Database (or the part of it we're interested in).
 Using it, the libovsdb.client package is able to properly encode and decode OVSDB messages
 and store them in Model instances.
 A client instance is created by simply specifying the connection information and the database model:
 
-     ovs, _ := client.Connect(context.Background(), clientDBModel)
+	ovs, _ := client.Connect(context.Background(), clientDBModel)
