+
+This is a [Godot](https://godotengine.org/) plugin which allows one to make planning  annotations and sketches directly in the 2D editor, without affecting runtime visuals, using a custom 'AnnotateCanvas' node.

+## Features
+
+### Annotate
+
+Annotate with variable brush size and color directly in the 2D editor using the 'AnnotateCanvas' node.
+
+![Annotate Example](examples/Annotate.gif)
+
+### Polygon Mode
+
+Use polygon mode to draw straight lines between clicks.
+
+![Polygon Mode Example](examples/AnnotatePoly.gif)
+
+### Erase
+
+Erase any previously drawn annotate strokes.
+
+![Erase Example](examples/Erase.gif)
+
+### Control Annotation Visibility
+
+Only show annotations in the 2D editor (optionally show in run mode).
+
+![Visibility Example](examples/Visibility.gif)
+
+### Save Canvas As Image
+
+Save the canvas to disk as an image file.
+
+![Save To Disk Example](examples/SaveToDisk.gif)
+
+## Usage
+
+To start annotating, add the 'AnnotateCanvas' node to a godot scene.
+
+### Controls
+
+**Left Mouse Button**
+: Annotate on the currenty selected 'AnnotateCanvas' node.
+
+**Alt + Left Mouse Button**
+: Annotate on the currently selected 'AnnotateCanvas' node using the polygon mode.
+
+**Right Mouse Button**
+: Erase annotate strokes on the currently selected 'AnnotateCanvas' node.
+
+**Shift + Mouse Scroll**
+: Change brush size.
+
+**Shift + Alt + S**
+: Save the selected 'AnnotateCanvas' to disk as an image.
+
+### Locking
+
+Locking an 'AnnotateCanvas' node does not prevent it from being drawn on, instead toggle the 'Advanced > Lock Canvas' property to prevent this.
+
+## Installing
+
+See [Installing Plugins](https://docs.godotengine.org/en/stable/tutorials/plugins/editor/installing_plugins.html), for how to add this plugin to your Godot project.
