+## Requirement
+- https://github.com/Fannovel16/comfyui_controlnet_aux
 
-## Architecture
-### Front-End node
-- Stores the json pose object
-- Call `/openpose/render` API endpoint to convert json to image
-- Preview the pose image
-- Display an edit button to trigger the editor modal
-  -  On click: send the json pose to editor
-  - On editor close: receive the updated json and update preview
-- Input: [Optional] Background image
-- Output: Pose Image
+## How to use
+### Step 1: Use pose estimator node to obtain `POSE_KEYPOINT` JSON
