Update Nodes Whitelist

To add a node to the nodes whitelist:

1. In the Whitelisted Nodes tab of the Permissioning Management Dapp, click the Add Whitelisted Nodes button. The add node window is displayed.

2. Enter the enode URL of the node to be added and click the Add Whitelisted Node button.

To remove a node from the nodes whitelist:

1. In the Whitelisted Nodes tab of the Permissioning Management Dapp, hover over the row of the node to remove. A trash can is displayed.

2. Click on the trash can.

!!! tip If you add a running node, the node does not attempt to reconnect to the bootnode and synchronize until peer discovery restarts. To add a whitelisted node as a peer without waiting for peer discovery to restart, use admin_addPeer.

If the node is added to the whitelist before starting the node, using `admin_addPeer` is not required because
peer discovery is run on node startup. 

Update Accounts Whitelists

To add an account to the accounts whitelist:

1. In the Whitelisted Accounts tab of the Permissioning Management Dapp, click the Add Whitelisted Account button. The add account window is displayed.

2. Enter the account address in the Account Address field and click the Add Whitelisted Account button.

To remove an account from the accounts whitelist:

1. In the Whitelisted Accounts tab of the Permissioning Management Dapp, hover over the row of the account to be removed. A trash can is displayed.

2. Click on the trash can.

Update Admins

Admins are added or removed in the same way as accounts except in the Admin Accounts tab.
