If you don't have a keyboard or screen connected to Raspberry Pi, you can use this network link to remotely access Raspberry Pi just as you would on a normal network (just use the new IP address you have set for the connection). Refer to the Connecting remotely to Raspberry Pi over the network using VNC and Connecting remotely to Raspberry Pi over the network using SSH (and X11 Forwarding) recipes.
There is lots of additional information available on my website, https://pihw.wordpress.com/guides/direct-network-connection, including additional troubleshooting tips and several other ways to connect to your Raspberry Pi without needing a dedicated screen and keyboard.
