 Usage
 -----
 
 In order to centralize state of locks, you first need to create a ``Store``.
 Then, you can ask to this store to create a Lock for your ``resource``.
 
 The :method:`Symfony\\Component\\Lock\\LockInterface::acquire` method tries to
-acquire the lock. If the lock is can not be acquired, the method throws a
