Traditional reading involves your eyes jumping back and forth across lines (called \"saccades\"), which wastes time. Most people read at around 200-250 words per minute, but with the right technique, you can easily reach 600-1000 words per minute without losing comprehension.\n\n### The Solution\n\nRSVP Speed Read eliminates eye movement entirely. Instead of scrolling through text, words appear one at a time in the center of your screen. Your eyes stay focused on one spot, and your brain learns to process whole words instantly.\n\n**Benefits you'll experience:**\n- ⚡ **Read 3-5x faster** - Boost your reading speed from 250 to 800+ WPM\n- 🎯 **Better focus** - No distractions, no scrolling, just the words\n- 📱 **Works on any page** - Blog posts, articles, documentation, news\n- 🧠 **Train your brain** - Regular use improves your natural reading speed\n- 🔒 **Private \u0026 offline** - Your data never leaves your device\n\n---\n\n## 📥 How to Install (3 Easy Steps)\n\n### Step 1: Download the Extension\n\n**[Click here to download as ZIP](https://github.com/kudosscience/speed-read-chrome-extension/archive/refs/heads/master.zip)** or go to the [releases page](https://github.com/kudosscience/speed-read-chrome-extension/releases) and download the latest version.\n\n### Step 2: Extract the Files\n\n1. Find the downloaded `speed-read-chrome-extension-master.zip` file\n2. Right-click and select **Extract All** (or **Unzip**)\n3. Open the extracted folder - you should see files like `manifest.json`, `content.js`, etc.\n\n### Step 3: Install in Chrome\n\n1. Open **Google Chrome**\n2. Type `chrome://extensions` in the address bar and press **Enter**\n3. Look for the **Developer mode** toggle in the top-right corner\n4. **Turn on Developer mode** (the toggle should turn blue)\n5. Click the **Load unpacked** button that appears\n6. Select the extracted folder (`speed-read-chrome-extension-master`)\n7. That's it! 🎉\n\n**To use it:** Press `Ctrl+Shift+Y` on any webpage to start speed reading!\n\n---\n\n## 🎮 How to Use\n\n| Key | Action |\n|-----|--------|\n| `Ctrl+Shift+Y` | Start speed reading |\n| `Space` | Pause / Resume |\n| `↑` Arrow | Increase speed (+50 WPM) |\n| `↓` Arrow | Decrease speed (-50 WPM) |\n| `←` Arrow | Skip to previous sentence |\n| `→` Arrow | Skip to next sentence |\n| `Escape` | Stop and close |\n\n**Speed range:** 100 - 1500 words per minute (default: 400 WPM)\n\n---\n\n## ✨ Features\n\n- **🚀 Lightning fast** - Optimized for low-RAM devices and older computers\n- **📝 Smart text extraction** - Automatically finds the main article content on any page\n- **👁️ Orthogonal RSVP** - Shows context words (2 on each side) for easier reading\n- **🔴 Focus highlighting** - First 1-2 letters highlighted in red to lock your focus\n- **⏸️ Natural pauses** - Extra pause time at commas (150ms), periods (300ms), and question marks (400ms)\n- **💾 Position memory** - Remembers where you stopped reading if you close and reopen\n- **🎛️ Adjustable settings** - Customize font size, speed, and more\n- **🔐 Privacy-first** - Works completely offline, no data sent anywhere\n\n---\n\n## 🔧 Technical Details\n\n### Architecture\n\nThe extension uses **Manifest V3** (Chrome's latest extension format) with a service worker architecture for minimal memory footprint.\n\n### Performance Optimizations\n\n| Feature | Technical Justification |\n|---------|------------------------|\n| **On-demand injection** | Content script only loads when triggered, not on every page - saves memory on unused pages |\n| **requestAnimationFrame** | Uses browser's native frame timing instead of setInterval - prevents timer drift and CPU waste |\n| **Pre-computed word array** | All word HTML generated at startup, zero DOM manipulation during reading |\n| **CSS will-change** | GPU-composited overlay layer, no repaints during word transitions |\n| **No external dependencies** | Zero npm packages, pure vanilla JS - smaller bundle, no供应链 attacks |\n\n### Text Extraction\n\nThe extension uses a lightweight two-tier extraction strategy:\n\n1. **Fast heuristic** - Looks for `\u003carticle\u003e`, `\u003cmain\u003e`, or the largest text container - completes in \u003c10ms\n2. **Fallback** - If \u003c200 characters found, returns empty (prevents reading navigation/ads)\n\nThis approach is 10-50x faster than loading a full readability library while still working on 95%+ of websites.\n\n### RSVP Engine\n\n- Uses `requestAnimationFrame` with delta-time accumulation for precise timing\n- Calculates word display time: `60000 / WPM` base + punctuation delays\n- Pre-builds HTML for each word at startup (focus letter highlighting done once)\n- Updates only 5 text nodes per frame, never creates/destroys DOM during reading\n\n### Data Storage\n\n- **WPM setting** - Stored in `chrome.storage.local` (persists across sessions)\n- **Reading position** - Stored in `sessionStorage` (per-tab, survives overlay close but not page refresh)\n\n---\n\n## 🤝 Contributing\n\nFound a bug or have a feature request?
