 This tool transforms tag properties in JSON files by replacing the first value in the `tagProps` array with a path based on the element's name, an MCM number, and a device type.
 
-## Usage
+## MCM Folder Organization
+
+The tool can also organize tags according to MCMs (Master Control Modules) in your Ignition project. This process will:
+1. Process all MCM folders in your Detailed-Views directory
+2. Update view.json files with proper tag paths
+3. Generate a consolidated tags.json file with all MCM tag structures
+
+### Usage for MCM Organization
+
+```bash
+python process_tags.py "C:\Program Files\Inductive Automation\Ignition\data\projects\YOUR_PROJECT\com.inductiveautomation.perspective\views\Detailed-Views" -o "outputs"
+```
+
+Replace `YOUR_PROJECT` with your actual Ignition project name.
+
+### Example:
+
+```bash
+python process_tags.py "C:\Program Files\Inductive Automation\Ignition\data\projects\MTN6_SCADA\com.inductiveautomation.perspective\views\Detailed-Views" -o "outputs"
+```
+
+This will:
+1. Scan all MCM folders in the Detailed-Views directory
+2. Process each view.json file in the MCM folders
+3. Update the view.json files with proper tag paths
+4. Generate a consolidated tags.json file in the outputs directory
+
+### Output Structure
+
+The generated tags.json file will contain:
+- All MCMs from your Detailed-Views folder
+- Properly organized tag structures for each MCM
+- Merged tags for MCMs that have multiple folders (e.g., MCM02 with both "Fluid Inbound Merges 5-7" and "Fluid Inbound Upper")
+
+## Single File Transformation
+
+For transforming individual JSON files:
 
 ```bash
 python tag_transformer.py <input_file.json> <mcm_number> [device_type]
