+Package client is a Go client for the Nextcloud Provisioning API.
+
+For more information about the Provisioning API, see the documentation:
+https://docs.nextcloud.com/server/13/admin_manual/configuration_user/user_provisioning_api.html
+
+Usage
+
+You use the library by creating a client object and calling methods on it.
+
+For example, to list all the Nextcloud's instance users:
+
+	package main
+
+	import (
+		"fmt"
+		"github.com/partitio/gonextcloud/client"
+	)
+
+	func main() {
+		url := "https://www.mynextcloud.com"
+		username := "admin"
+		password := "password"
+		c, err := client.NewClient(url)
+		if err != nil {
+			panic(err)
+		}
+		if err := c.Login(username, password); err != nil {
+			panic(err)
+		}
+		defer c.Logout()
+
+		users, err := c.UserList()
+		if err != nil {
+			panic(err)
+		}
+		fmt.Println("Users :", users)
+	}
