+Configuration

+``utensor-cli`` use ``toml`` as configuration format.
+
+You can generate configuration file of given target as following:

+.. code-block:: console
+
+  $ utensor-cli generate-config --target <target name> [-o filename.toml]
+
+This command will generate a ``toml`` file listing all configurable values with its defaults.
