 The quantum package has no executable out of the box. You need to install (and then compile) some modules. The `qp_module.py` will help you.
 
 ```
-      Usage: qp_module.py list (--installed|--avalaible-local|--avalaible-remote)
-       qp_module.py install <name>...
-       qp_module.py create -n <name> [<children_module>...]
+       qp_module.py create -n <name> [<children_modules>...]
        qp_module.py download -n <name> [<path_folder>...]
+       qp_module.py install <name>...
+       qp_module.py list (--installed | --available-local)
+       qp_module.py uninstall <name>
+
 ```
 
  For exemple you can type : `qp_module.py install Full_CI`. This will install the `Full_CI` module. All the modules are installed in the `$QP_ROOT/src/`, and all the available modules are in `$QP_ROOT/plugins/`
