-## Share Dependencies accross Commands
+## Share dependencies across commands
 It is possible to share dependencies with the command functions `c.SetDependency(name, dep)` and `dep, err := c.GetDependency(name)`.
 If you for instance initialize a logger in the root command and register it as dependency every sub-command has
 access to it. Keep in mind that dependencies are saved as `interface{}` so you have to take care of asserting the right type.
