-# Collector generator
-Generates a collector skeleton implementation from a WMI class. 
-
-## Usage
-Build the generator:
-
-```bash
-go build .
-```
-
-Run the script to query the WMI service and send the output to the generator:
-
-```powershell
-.\New-Collector.ps1 -Class Win32_PerfRawData_PerfOS_Processor
-```
-
-This will generate a collector. The collector name is generated by first removing `Win32_PerfRawData_Perf` and lower-casing, so `Win32_PerfRawData_PerfOS_Processor` will generate `os_processor.go`. This can be overridden by passing `-CollectorName` to the script.
