Add new user for SSH

Laravel doesn't like it when you run it in root, this is for security purposes. We agree with them it's safer, however you can use root.

adduser ticaga

This creates a user called "ticaga". You should have created a password whilst you added a user.

usermod -aG sudo ticaga

This allows you to add the user "ticaga" to the sudo group, this allows you to use sudo.
