There isn't a standard method to do it, but you need to determine how to route and connect each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this, place a diode on each key switch pin and then solder it. This will protect the pins on the key switch from current and prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and it comes with a an indicator in black that indicates which way the current will flow.
