+# Frames
+
+## Ordering
+
+Frames should be ordered where frame children come first, followed by the frame element itself:
+
+```
+[
+  other_element,
+  frame1_child1,
+  frame1_child2,
+  frame1,
+  other_element,
+  frame2_child1,
+  frame2_child2,
+  frame2,
+  other_element,
+  ...
+]
+```
+
+If not ordered correctly, the editor will still function, but the elements may not be rendered and clipped correctly. Further, the renderer relies on this ordering for performance optimizations.

+# JSON Schema
+
+The Excalidraw data format uses plaintext JSON.
+
+## Excalidraw files
+
+When saving an Excalidraw scene locally to a file, the JSON file (`.excalidraw`) is using the below format.
+
+### Attributes
+
+| Attribute | Description | Value |
+| --- | --- | --- |
+| `type` | The type of the Excalidraw schema | `"excalidraw"` |
+| `version` | The version of the Excalidraw schema | number |
+| `source` | The source URL of the Excalidraw application | `"https://excalidraw.com"` |
+| `elements` | An array of objects representing excalidraw elements on canvas | Array containing excalidraw element objects |
+| `appState` | Additional application state/configuration | Object containing application state properties |
+| `files` | Data for excalidraw `image` elements | Object containing image data |
+
+### JSON Schema example
+
+```json
+{
+  // schema information
+  "type": "excalidraw",
+  "version": 2,
+  "source": "https://excalidraw.com",
+
+  // elements on canvas
+  "elements": [
+    // example element
+    {
+      "id": "pologsyG-tAraPgiN9xP9b",
+      "type": "rectangle",
+      "x": 928,
+      "y": 319,
+      "width": 134,
+      "height": 90
+      /* ...other element properties */
+    }
+    /* other elements */
+  ],
+
+  // editor state (canvas config, preferences, ...)
+  "appState": {
+    "gridSize": 20,
+    "viewBackgroundColor": "#ffffff"
+  },
+
+  // files data for "image" elements, using format `{ [fileId]: fileData }`
+  "files": {
+    // example of an image data object
+    "3cebd7720911620a3938ce77243696149da03861": {
+      "mimeType": "image/png",
+      "id": "3cebd7720911620a3938c.77243626149da03861",
+      "dataURL": "data:image/png;base64,iVBORWOKGgoAAAANSUhEUgA=",
+      "created": 1690295874454,
+      "lastRetrieved": 1690295874454
+    }
+    /* ...other image data objects */
+  }
+}
+```
+
+## Excalidraw clipboard format
+
+When copying selected excalidraw elements to clipboard, the JSON schema is similar to `.excalidraw` format, except it differs in attributes.
+
+### Attributes
+
+| Attribute | Description | Example Value |
+| --- | --- | --- |
+| `type` | The type of the Excalidraw document. | "excalidraw/clipboard" |
+| `elements` | An array of objects representing excalidraw elements on canvas. | Array containing excalidraw element objects (see example below) |
+| `files` | Data for excalidraw `image` elements. | Object containing image data |
