 ## Usage of a vehicle variant specific signal tree
 The output from the HIM configurator is the selected parts of the "vspec super tree" in a file with one of the supported formats.
-This file can then e. g. be used in a vehicle of the selected variant by a server that is controlling the access to the signals.
-The server cn then use the tree to "vet" client request - checking that the signal is present, whether it is read-only or read-write, etc.

+The server can then use the tree to "vet" client request - checking that the signal is present, whether it is read-only or read-write,

 An example of a server using it like this is the [VISS reference server](https://github.com/COVESA/vissr).
