+        import velopack

+        if __name__ == "__main__":
+            # Velopack builder needs to be the first thing to run in the main process.

+
+        Velopack provides a simple way to check for updates and apply them. 
+        The following shows how to implement a basic update check within your application. 
+        
+        You can also split up the various methods to allow your users to control when to check for updates, download them, or apply them.
+
+        ```python
+        def update_app():
+            manager = velopack.UpdateManager("https://the.place/you-host/updates")
+
+            update_info = manager.check_for_updates()
+            if not update_info:
+                return # no updates available
+
+            # Download the updates, optionally providing progress callbacks
+            manager.download_updates(update_info)
+
+            # Apply the update and restart the app
+            manager.apply_updates_and_restart(update_info)
+        ```

+
+        Compile your app to a binary (eg. `.exe` on Windows). Example using PyInstaller:
+        ```sh
+        pyinstaller --onedir app.py
+        ```
