no-auth description error in readme

[glebsts]

Hello,
Thank you for your tool!
README contains following:

If your docker registry does not need credentials, you will need to send this HEADER:
Access-Control-Allow-Origin: '*'

But that leads to line 16: cannot unmarshal !!str * into []string, because this parameter is expected to be an array. Later you have valid example of Access-Control-Allow-Origin: ['http://127.0.0.1:8001']
So it must be
Access-Control-Allow-Origin: ['*']
At least that worked for me.
