First, determine the name of the WiFi interface:

$ nmcli d
DEVICE             TYPE      STATE         CONNECTION
...
wlan0              wifi      disconnected     --

Make sure the WiFi radio is on (which is its default state):

$ nmcli r wifi on

Then, list the available WiFi networks:

$ nmcli d wifi list
*  SSID           MODE   CHAN  RATE       SIGNAL  BARS  SECURITY
   ...
   my_wifi      Infra  5     54 Mbit/s  89      ▂▄▆█  WPA2

As an example, to connect to the access point 'my_wifi', you would use the following command:

$ nmcli d wifi connect my_wifi password <password>

<password> is the password for the connection which needs to have 8-63 characters or 64 hexadecimal characters to specify a full 256-bit key.
