Hi, I am new to the github. I tryed to commit my project. but has occured following error on My cmd.

*** Please tell me who you are.

Run

  git config --global user.email “you@example.com

to set your account’s default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got ‘Sama@Sama-PC.(none)’)
