 Usage:
 
 ```lucee
-dir = directoryList("git:///path/inside/git");
+dir = directoryList("git:///path/inside/repo");
 ```
 
 Credentials can't be in the path (security), but branch and repository can:
 
 ```lucee
-dir = directoryList("git://master@/path/inside/git!lucee-examples");
+dir = directoryList("git://master@github.com/lucee/lucee-examples!/path/inside/repo");
 dump(dir);
 ```
 
 ### Pattern
 
-`git://[{branch}@]/{path-inside-git}[!{repository}]` e.g. `git://master@/path/inside/git!lucee-examples`
+`git://[{branch}@][{repository}]!/{path-inside-repo}` e.g. `git://master@github.com/lucee/lucee-examples!/path/inside/repo`
