2. Edit file on the following path

/etc/rc.local

3. Add below line above exit 0

systemctl start ssh #this will run on each startup

or

systemctl enable ssh #this will enable ssh on each startup.

4. Remove SD Card from computer, insert in RPi and boot up

5. Find IP address of the RPi from your routers DHCP lease table

6. Connect SSH to access RPi. Default credentials are

username: pi
password: raspberry

Method 2
1. Mount SD card to computer, open the boot partition.

2. Create file ssh (without extension) onto the boot partition of the SD card

3. Remove SD Card from computer, insert in RPi and boot up

4. Find IP address of the RPi from your routers DHCP lease table
