-## Recent updates
+## Use
+
+Select an option from the Image Ratio dropdown. This will lock the height slider to the width slider. To unlock the sliders select None from the dropdown. Select the magnifying glass to attempt to identify the Ratio based on the current width and heights.
+
+NOTICE: Currently the way that gradio callbacks work this only works when the width changes. Also since this is a client to server to client solution the order of operations sometimes gets missed. (i.e. It requires you to jiggle the width slider to get the correct height)
+
+## Roadmap
+
+- Allow for custom ratios
+- Increase tolerance for the find button
