-user.email::
-	Your email address to be recorded in any newly created commits.

-user.useConfigOnly::
-	Instruct Git to avoid trying to guess defaults for `user.email`
-	and `user.name`, and instead retrieve the values only from the
-	configuration. For example, if you have multiple email addresses
-	and would like to use a different one for each repository, then
-	with this configuration option set to `true` in the global config
-	along with a name, Git will prompt you to set up an email before
-	making new commits in a newly cloned repository.
-	Defaults to `false`.

-user.signingKey::
-	If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
-	key you want it to automatically when creating a signed tag or
-	commit, you can override the default selection with this variable.
-	This option is passed unchanged to gpg's --local-user parameter,
-	so you may specify a key using any method that gpg supports.
