IPFS, Windows 10 error, Error: invalid 'ipfs ref' path

Downloaded Version v0.4.18 for windows 64bit
After downloading, unziped the archive, and moved ipfs.exe somewhere in my%PATH%
Receive error in GitBash (preferred tool) and Windows command line

Receive error when running command:
ipfs cat /ipfs/my-peer-identity-id/readme

Error: invalid ‘ipfs ref’ path

I am able to run following commands:
ipfs help
ipfs init
which ipfs
ipfs commands
ipfs version --help

That’s not a valid /ipfs/ path. IPNS paths can include your peer ID, but IPFS paths are determined by the content and structure of objects.
