 If there are other repositories that you also use frequently, you can
 create similar configuration options to save typing; for example,
-after
 
 -------------------------------------------------
-$ git config remote.example.url git://example.com/proj.git
+$ git remote add example git://example.com/proj.git
 -------------------------------------------------
 
-then the following two commands will do the same thing:
+adds the following to `.git/config`:
 
 -------------------------------------------------
-$ git fetch git://example.com/proj.git master:refs/remotes/example/master
-$ git fetch example master:refs/remotes/example/master
+[remote "example"]
+	url = git://example.com/proj.git
+	fetch = +refs/heads/*:refs/remotes/example/*
 -------------------------------------------------
 
-Even better, if you add one more option:
-
--------------------------------------------------
-$ git config remote.example.fetch master:refs/remotes/example/master
--------------------------------------------------
