+## 📖 Overview
+
+In `PortProtonQT`, you can change:
+
+- Game title
+- Description
+- Cover image
+
+Override types:
+
+| Type            | Location                                        | Priority |
+|-----------------|--------------------------------------------------|----------|
+| User            | `~/.local/share/PortProtonQT/custom_data/`       | Highest  |
+| Built-in        | `portprotonqt/custom_data/`                      | Lower    |

+
+## ⚙️ How It Works
+
+### Data Priorities
+
+Data is used in the following order:
+
+1. **User Overrides**
+2. **Built-in Overrides**
+3. **Steam Metadata**
+4. **`.desktop` file info**
+
+### File Structure
+
+Each `<exe_name>` folder can include:
+
+- `metadata.txt` — contains name and description:
+  ```txt
+  name=My Game Title
+  description=My Game Description
+  ```
+- `cover.<extension>` — image file (`.png`, `.jpg`, `.jpeg`, `.bmp`)
+
+---
+
+## 👤 For Users
+
+### Creating User Overrides
+
+1. **Create a folder for your game**:
+   ```bash
+   mkdir -p ~/.local/share/PortProtonQT/custom_data/mygame
+   ```
+
+2. **Add overrides**:
+   - **Metadata file**:
+     ```bash
+     echo -e "name=My Game\ndescription=Exciting game" > ~/.local/share/PortProtonQT/custom_data/mygame/metadata.txt
+     ```
+   - **Cover image**:
+     ```bash
+     cp ~/Images/custom_cover.png ~/.local/share/PortProtonQT/custom_data/mygame/cover.png
+     ```
+
+3. **Restart PortProtonQT**.
+
+## 🛠 For Developers
+
+### Adding Built-In Overrides
+
+1. **Create a folder in the project**:
