+
+## 🚀 Quick Start
+
+### Using Confitty
+
+1. **Open** [confitty.app](https://confitty.app) (or run locally)
+2. **Navigate** using the sidebar to explore config categories
+3. **Customize** settings – preview updates instantly
+4. **Review** raw output in the **Config** tab
+5. **Export** your `kitty.conf` file
+
+### Applying Your Config
+
+```bash
+# Save to Kitty config directory
+mkdir -p ~/.config/kitty
+cp kitty.conf ~/.config/kitty/
+
+# Reload Kitty without restarting
+# Press: Ctrl+Shift+F5
+```
+
+> **Note:** If you've remapped the reload shortcut, use your custom binding. See [Kitty keyboard shortcuts](https://sw.kovidgoyal.net/kitty/actions/).
+
+### 📥 Importing Existing Configs
+
+Click **Import** and select your `kitty.conf`. Confitty parses it and populates the visual editor. 
+
+Complex configs (custom kittens, include directives, environment variables) are preserved in the output even if they don't map to visual controls.
+
+## ⚙️ How It Works
+
+Confitty uses a **smart diff algorithm** that exports only settings that differ from Kitty's defaults:
+
+- **Change font size** from 11 to 14? → Output includes `font_size 14`
+- **Leave it at 11?** → Not included in output
+
+This approach:
+- ✅ Keeps configs readable and minimal
+- ✅ Avoids overriding defaults that may change between Kitty versions
+- ✅ Makes it easy to see what you've customized
+
+The exported file includes a header with generation date, config path, and reload shortcut reminder.
