What are ways to make Google Chrome start in incognito mode by default?

I found one way:
Use mouse to right click on the Chrome desktop icon or the icon you use to launch Chrome. Go to icon Properties.
In properties change the target URL to Google Chrome .exe file.

From example:
M:\GoogleChromePortable\GoogleChromePortable.exe

To example:
"M:\GoogleChromePortable\GoogleChromePortable.exe" -incognito
