+# Frequently Asked Questions (FAQ)
+
+## How do I release and distribute my Desktop application?
+
+### Creating an Installer
+
+To create a distributable installer for your Desktop application, use the following command:
+
+```bash
+mix desktop.installer
+```
+
+This command will create platform-specific installers for Windows, macOS, and Linux that you can distribute to your users.
+
+### About `mix release`
+
+While `mix release` is a standard Elixir command for creating releases, it's not the recommended approach for Desktop applications. The `mix release` command creates a standalone Erlang release, but it doesn't include the platform-specific packaging and UI components needed for a Desktop application.
+
+### Distribution
+
+After running `mix desktop.installer`, you'll find the installer files in your project's build directory. These are the files you should distribute to your users:
+
+- **Windows**: `.exe` installer file
+- **macOS**: `.dmg` or `.app` bundle
+- **Linux**: `.AppImage`, `.deb`, or `.rpm` package
+
+Users can simply download and run these installers to install your application on their system.
+
+### Getting Started
+
+If you're new to Elixir Desktop:
+
+1. Follow the [Getting your Environment Ready Guide](getting_started.md) to set up your development environment
+2. Create your first app with the [Your first Desktop App Guide](your_first_desktop_app.md)
+3. When ready to distribute, run `mix desktop.installer` to create platform-specific installers
