+# Getting Started
+
+1. Install the plugin through the Godot AssetLib or clone the repository and drag the `addons/block_code/` directory into your project's `res://addons/` directory.
+
+2. Make sure to enable the plugin in `Project > Project Settings > Plugins`
+
+3. You're ready to get started! Open a scene, and add a `BlockCode` child node to any node in the scene using the `Add Child Node` menu dialog.
+
+4. The Block Code editor will open in a new tab. Drag blocks from the picker and snap them together to create a script. You can switch to other Block Code scripts by clicking the respective `BlockCode` node in the scene tree.
+
+5. Run the scene to see your Block Code scripts in action. Block Code scripts are attached to the `BlockCode` node's parent, and are saved to the scene.
