+Optional arguments
+------------------
+
+NAPALM supports passing certain optional arguments to some drivers. To do that you have to pass a dictionary via the
+:code:`optional_args` parameter when creating the object::
+
+    >>> from napalm import get_network_driver
+    >>> driver = get_network_driver('eos')
+    >>> optional_args = {'my_optional_arg1': 'my_value1', 'my_optional_arg2': 'my_value2'}
+    >>> device = driver('192.168.76.10', 'dbarroso', 'this_is_not_a_secure_password', optional_args=optional_args)
+    >>> device.open()
+
+List of supported optional arguments
+____________________________________
+
+* :code:`port` (vyos) - Allows you to specify a port other than the default.
+* :code:`key_file` (vyos) - Netmiko/Paramiko argument, path to a private key file (default: 'False').
+
+
+
+Prerequisites
+-------------
+
+
+VyOS has no native HTTP API or NETCONF capability.
+We are using Netmiko for ssh connections and scp file transfers.
+Having Netmiko installed in your working box is a prerequisite.
+
+VyOS in version 1.1.x (tested 1.1.7)
+
+napalm==2.*
+paramiko
+netmiko>=1.1.0
+vyattaconfparser
+
+
+
+Configuration file
+------------------
+
+Currently VyOS driver supports two different configuration formats:
+* load_replace_candidate - Full config file (with brackets) like in /config/config.boot
+Due to the OS nature,  we do not support a replace using
+a set-style configuration format.
+* load_merge_candidate - Currently driver supports set-style configuration format.
+Example
+
+`set system login banner pre-login "test"`
+
+Vyos require configuration file (load_replace) to contain comment like following
+
+`/* Warning: Do not remove the following line. */
+/* === vyatta-config-version: "cluster@1:config-management@1:conntrack-sync@1:conntrack@1:cron@1:dhcp-relay@1:dhcp-server@4:firewall@5:ipsec@4:nat@4:qos@1:quagga@2:system@6:vrrp@1:wanloadbalance@3:webgui@1:webproxy@1:zone-policy@1" === */
+/* Release version: VyOS 1.1.7 */`
+
+Otherwise VyOS reject `load` operation
+
+Notes
+------------------
+* The NAPALM-vyos driver supports all Netmiko arguments as either standard arguments (hostname, username, password, timeout) or as optional_args (everything else).
+
+* The NAPALM-vyos driver supports authentication with ssh key. Please specify path to a key in optional_args
+`'optional_args': {'key_file': '/home/user/ssh_private_key'}`
