 3.  **Assumed Permissions**: Extensions may assume they have access to macOS-specific permissioned data (like Contacts or Calendars) which have no direct equivalent.
 
-## 🚀 Getting Started
+## 🚀 Installation
 
-To get the project running locally, you'll need to set up the development environment.
+You can download the latest release from the [GitHub Releases page](https://github.com/ByteAtATime/raycast-linux/releases).
+
+Currently, only an `.AppImage` is provided. After downloading, make it executable:
+
+```bash
+chmod +x <downloaded-file-name>.AppImage
+./<downloaded-file-name>.AppImage
+```
+
+### System Requirements
+
+The application requires `glibc` version **2.38**, which is installed by default on Ubuntu 24.04, Fedora 40, and recent versions of Arch Linux.
+
+**Wayland users:** For the global snippet expansion feature to work, the application needs permission to read keyboard events. The recommended and most secure method is to add a `udev` rule.
+
+1. Create the `udev` rule file:
+
+   ```bash
+   sudo nano /etc/udev/rules.d/99-raycast-linux.rules
+   ```
+
+2. Add the following line to the file:
+   This rule grants the user at the physical console access to keyboard devices.
+
+   ```
+   KERNEL=="event*", ENV{ID_INPUT_KEYBOARD}=="1", TAG+="uaccess"
+   ```
+
+3. Reload the `udev` rules to apply the changes:
+   ```bash
+   sudo udevadm control --reload-rules && sudo udevadm trigger
+   ```
+
+## 🛠️ Building from Source
+
+If you prefer to build the project from its source code, you'll need to set up the development environment.
