-# ComfyUI_JSON_Helper
- Simple custom node for ComfyUI that converts JSON strings to JSON objects.
+# ComfyUI JSON Helper
+
+This custom node for ComfyUI provides a simple way to convert JSON strings to JSON objects, bridging the gap between nodes that output JSON as strings and nodes that require JSON object inputs.
+
+## Features
+
+- Converts JSON strings to JSON objects
+- Handles JSON parsing errors gracefully
+- Easy to integrate into existing ComfyUI workflows
+
+## Installation
+
+1. Navigate to your ComfyUI custom nodes folder:
+   ```
+   cd /path/to/ComfyUI/custom_nodes/
+   ```
+2. Clone this repository:
+   ```
+   git clone https://github.com/yourusername/ComfyUI-JSONHelper.git
+   ```
+3. Restart ComfyUI
+
+## Usage
+
+After installation, you'll find a new node called "JSON String to Object" in the node menu. 
+
+1. Connect the output of a node that produces a JSON string to the input of this node.
+2. The output of this node will be a JSON object, which can be connected to nodes that expect JSON input.
+
+## Error Handling
+
+If the input string is not valid JSON, the node will print an error message to the console and return None.
