+   - Note down the API URL and the API key, as you’ll need these for your frontend application.
+
+## Tutorial with an Example Project
+
+### Example Project: Todo List Application
+
+In this tutorial, we’ll build a simple Todo List application using Supabase and React.
+
+### Steps
+
+1. **Initialize a React Application**
+   - Open your terminal and run the following command to create a new React application:
+
+     ```bash
+     npx create-react-app supabase-todo
+     cd supabase-todo
+     ```
+
+2. **Install Supabase Client**
+   - Inside your React project directory, install the Supabase client:
+
+     ```bash
+     npm install @supabase/supabase-js
+     ```
+
+3. **Set Up Supabase Client**
+   - Create a new file named `supabaseClient.js` in the `src` directory and add the following code:
+
+     ```javascript
+     import { createClient } from '@supabase/supabase-js';
+
+     const supabaseUrl = 'https://your-supabase-url.supabase.co';
+     const supabaseKey = 'your-anon-key';
+
+     export const supabase = createClient(supabaseUrl, supabaseKey);
+     ```
+
+4. **Create a Database Table**
+   - In the Supabase dashboard, go to the SQL editor and run the following SQL to create a `todos` table:
+
+     ```sql
+     create table todos (
+       id bigint generated by default as identity primary key,
+       task text not null,
+       is_complete boolean default false
+     );
+     ```
+
+5. **Fetch Todos from Supabase**
+   - In your `App.js` file, import Supabase and fetch the todos:
+
+     ```javascript
+     import React, { useState, useEffect } from 'react';
+     import { supabase } from './supabaseClient';
+
+     function App() {
+       const [todos, setTodos] = useState([]);
+
+       useEffect(() => {
+         fetchTodos();
+       }, []);
+
+       const fetchTodos = async () => {
+         let { data: todos, error } = await supabase
+           .from('todos')
+           .select('*');
+         if (error) console.log('Error:', error);
+         else setTodos(todos);
+       };
+
+       return (
+         <div className="App">
+           <h1>Todo List</h1>
+           <ul>
+             {todos.map(todo => (
+               <li key={todo.id}>{todo.task}</li>
+             ))}
+           </ul>
+         </div>
+       );
+     }
+
+     export default App;
+     ```
+
+6. **Add a New Todo**
+   - Add a form to your `App.js` to allow adding new todos:
+
+     ```javascript
+     function App() {
+       const [todos, setTodos] = useState([]);
+       const [task, setTask] = useState('');
+
+       useEffect(() => {
+         fetchTodos();
+       }, []);
+
+       const fetchTodos = async () => {
+         let { data: todos, error } = await supabase
+           .from('todos')
+           .select('*');
+         if (error) console.log('Error:', error);
+         else setTodos(todos);
+       };
+
+       const addTodo = async (task) => {
+         let { data: todo, error } = await supabase
+           .from('todos')
+           .insert([{ task }]);
+         if (error) console.log('Error:', error);
+         else fetchTodos();
+       };
+
+       return (
+         <div className="App">
+           <h1>Todo List</h1>
+           <form onSubmit={(e) => {
+             e.preventDefault();
+             addTodo(task);
+             setTask('');
+           }}>
+             <input
+               type="text"
+               value={task}
+               onChange={(e) => setTask(e.target.value)}
+               placeholder="Add a new task"
+             />
+             <button type="submit">Add</button>
+           </form>
+           <ul>
+             {todos.map(todo => (
+               <li key={todo.id}>{todo.task}</li>
+             ))}
+           </ul>
+         </div>
+       );
+     }
+
+     export default App;
+     ```
