+# DOM Bookstore Project - Walkthrough
+
+## 📘 What You’re Building
+
+You’ll create a **Bookstore Web Application** using basic front-end tools:
+
+* 🧱 HTML for structure
+* 🎨 Tailwind CSS for styling
+* ⚙️ JavaScript for logic
+* 🔌 `fetch()` to interact with a real Bookstore API (GET, POST, DELETE)
+
+This guide is written like a class tutorial with simple language, perfect for beginners.
+
+---
+
+## 📁 1. Folder & File Setup
+
+### 🛠 Step-by-Step Setup
+
+1. Create a folder named `bookstore-project`
+2. Inside that folder, create these files:
+
+   * `index.html` → the web page
+   * `style.css` → styling rules
+   * `index.js` → your logic and interactivity
+3. (Optional) Create `.env` for API secrets (advanced)
+
+### ✅ Connect Everything
+
+In your `index.html` file, connect your CSS and JS like this:
+
+```html
+<head>
+  <title>Bookstore</title>
+  <link rel="stylesheet" href="style.css">
+  <script defer src="index.js"></script>
+</head>
+```
+
+Use the **Live Server** extension in VS Code to run your site in the browser.
+
+---
+
+## 🏗️ 2. Build Your HTML (Structure)
+
+This code goes in `index.html`. It sets up a form for adding books and a container to display them:
+
+```html
+<body>
+  <h1>📚 My Bookstore</h1>
+  <form id="book-form">
+    <input type="text" id="title" placeholder="Book Title" required>
+    <input type="text" id="author" placeholder="Author" required>
+    <button type="submit">Add Book</button>
+  </form>
+
+  <div id="books-container"></div>
+</body>
+```
+
+---
+
+## 🎨 3. Tailwind Styling (style.css)
+
+### Step 1: Add Tailwind CSS to your HTML
+
+Put this in the `<head>`:
+
+```html
+<script src="https://cdn.tailwindcss.com"></script>
+```
+
+### Step 2: Add Optional Custom Styles
+
+```css
+/* style.css */
+body {
+  font-family: sans-serif;
+  margin: 2rem;
+  background-color: #f9fafb;
+}
+```
+
+You’ll style your buttons, inputs, and divs using Tailwind utility classes in HTML.
+
+---
+
+## 🧠 4. JavaScript Logic (index.js)
+
+### 4.1 Access the DOM
+
+```js
+const form = document.getElementById('book-form');
+const booksContainer = document.getElementById('books-container');
+```
+
+### 4.2 Add a Book (POST Request)
+
+```js
+form.addEventListener('submit', function(e) {
+  e.preventDefault();
+  const title = document.getElementById('title').value;
+  const author = document.getElementById('author').value;
+
+  fetch('https://bookstore-api-six.vercel.app/books', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({ title, author })
+  })
+  .then(res => res.json())
+  .then(() => {
+    renderBooks();
+    form.reset();
+  });
+});
+```
+
+### 4.3 Load Books (GET Request)
+
+```js
+function renderBooks() {
+  booksContainer.innerHTML = '';
+  fetch('https://bookstore-api-six.vercel.app/books')
+    .then(res => res.json())
+    .then(books => {
+      books.forEach(book => {
+        const div = document.createElement('div');
+        div.classList.add('book-item');
+        div.innerHTML = `
+          <p><strong>${book.title}</strong> by ${book.author}</p>
+          <button onclick="deleteBook('${book.id}')">Delete</button>
+        `;
+        booksContainer.appendChild(div);
+      });
+    });
+}
+```
+
+### 4.4 Delete a Book (DELETE Request)
+
+```js
+function deleteBook(id) {
+  fetch(`https://bookstore-api-six.vercel.app/books/${id}`, {
+    method: 'DELETE'
+  })
+  .then(res => res.json())
+  .then(() => renderBooks());
+}
+```
+
+### 4.5 Start Everything on Load
+
+```js
+renderBooks();
+```
+
+---
+
+## 🔁 5. How the App Flows
+
+| Step | Action      | Code                                        |
+| ---- | ----------- | ------------------------------------------- |
+| 1️⃣  | Load page   | `renderBooks()` fetches books               |
+| 2️⃣  | Add book    | Form sends a `POST` → re-fetches books      |
+| 3️⃣  | Delete book | Button triggers `DELETE` → re-fetches books |
+
+All actions reflect live updates using the DOM.
+
+---
+
+## 💾 6. Bonus: Save to Local Storage
+
+```js
+function renderBooks() {
+  fetch('https://bookstore-api-six.vercel.app/books')
+    .then(res => res.json())
+    .then(books => {
+      localStorage.setItem('books', JSON.stringify(books));
+      displayBooks(books);
+    });
+}
+
+function displayBooks(books) {
+  booksContainer.innerHTML = '';
+  books.forEach(book => {
+    const div = document.createElement('div');
+    div.innerHTML = `<p>${book.title} by ${book.author}</p><button onclick="deleteBook('${book.id}')">Delete</button>`;
+    booksContainer.appendChild(div);
+  });
+}
+```
+
+---
+
+## 🧪 7. GitHub Workflow (Team Practice)
+
+1. Create a feature branch:
+
+   ```bash
+   git checkout -b add-form
+   ```
+2. Stage and commit:
+
+   ```bash
+   git add .
+   git commit -m "Add book form feature"
+   ```
+3. Push and make a Pull Request (PR):
+
+   ```bash
+   git push origin add-form
+   ```
+4. Get it reviewed → then merge to `main`
+
+---
+
+## 🚀 8. Deployment (Vercel or Netlify)
+
+1. Push your repo to GitHub
+2. Go to [vercel.com](https://vercel.com) or [netlify.com](https://netlify.com)
+3. Sign in, connect your repo, and deploy
+4. Share the live link!
