+\t- ## How to fix as a Contributor
+\t\t- drawings are located in <vault path>/draws
+\t\t- each ".excalidraw" drawing file should have an equivalent ".svg" file in <vault path>/assets/excalidraw_svg with the same basename
+\t\t- ### Example
+\t\t  ```
+\t\t  <vault path>/draws/2023-10-08-21-23-31.excalidraw
+\t\t  <vault path>/assets/excalidraw_svg/2023-10-08-21-23-31.svg
+\t\t  ```
+\t\t- to create a missing svg file, head to https://excalidraw.com/, paste the .excalidraw file, Click the Hamburger Menu > Export Image
+\t\t\t- Enable "Background" and check if you need Dark or Light theme
+\t\t\t- Click "SVG" and copy to <vault path>/assets/excalidraw_svgs
+\t\t\t- Rename the file so the base names match
