+# How to create the SSH key pair
+
+## Create the key pair
+Go into key pairs in the EC2 dashboard and create a new key pair. Download the .pem file and save it in the root of the project.
+
+![KeyPairs GUI](aws-ec2-key-pairs.png)
+Will automatically download a Private key
+![create-key-pair GUI](create-key-pair.png)
+Connect to the instance through AWS Instance Connect
+Now to connect key pairs to the EC2 instance, we need to add the Public key
+Write this and get the public key
+```bash
+ssh-keygen -y -f /path_to_downloaded_key-pair.pem
+```
+You will get a public key like this:
+![public-key GUI](cli-public-key.png)
+
+
+```bash
+sudo nano .ssh/authorized_keys
+```
+Now we need to add the public key into the EC2 instance, which we got running on the website through the AWS Instance connect terminal
+
+![AWS Instance connect terminal](aws-instance-connect-terminal.png)
+
+Now we need to reboot the EC2 Instance:

+
+## Connect to the EC2 instance
+We now need the private key to connect, so write this in your terminal
+```bash
+chmod 400 /path_to_downloaded_key-pair.pem
+```
+
+You can now connect to the Ubuntu instance, by writing this:
+```bash
+ssh -i "/path_to_downloaded_key-pair.pem" [email protected]
+```
