+This project is a code challenge task named ad Gambit-challenge 
+The folling are scripts and links how to operate it.
+## Technology
+### Frontend: React with JavaScript
+All the compontes, configs services utils for the task is bulid using react with JavaScrip to display the TUF-2000M energy meter reading.  
+### Backend: nodejs
+The 'api' folder hold the nodjs files for authentication user login. User information is saved in MySql. Controllers, middleware, routes are defined 
+### mysql database
+Users info(username, password, name ...) are saved in MySql.
+
+How to run the app
+1. npm start  form the src
+Runs the app in the development mode.\
+Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
+2. node server.js
+3. open Mysql and put sample data
+for creating users Table in demodb database
+CREATE TABLE `users` (
+  `userId` int NOT NULL AUTO_INCREMENT,
+  `name` varchar(45) NOT NULL,
+  `username` varchar(45) NOT NULL,
+  `password` varchar(45) NOT NULL,
+  `role` int NOT NULL,
+  `created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+  `updated` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+  `city` varchar(45) DEFAULT NULL,
+  `phone` varchar(45) DEFAULT NULL,
+  `email` varchar(45) DEFAULT NULL,
+  `country` varchar(45) DEFAULT NULL,
+  PRIMARY KEY (`userId`)
+) ENGINE=InnoDB AUTO_INCREMENT=4681 DEFAULT CHARSET=utf8mb3;
+SELECT * FROM demodb.users;
+
+### Version control: git
+used for version control and communicate with gitHub
+
+## Getting Started with Create React App
+Run the script in windows explorer or set the security of your browser
+For test the project you can see the local saved password in 
+
+In the project directory, you can run:
+../mockData/users.jsx # temporary username and password are saved there.
+
+N.b: this project is not build 
+### `npm run build`
+Builds the app for production to the `build` folder.\
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.\
+Your app is ready to be deployed!
+
+About development [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can't go back!**
