When the main screen comes up you can click the big button in the middle to connect or disconnect. There is also a button to choose the location of the server that you will use. As a user you would normally select a server close to you in order to get the best performance. This would be in the case that you want basic protection of your traffic. However if you are looking to masquerade your traffic as coming from another geography you can choose a remove country or location to connect to. So for example if you are in Germany but want to appear as though you are in the United States, you can connect to a server in New York, and then from there your traffic will be routed from New York to the internet (all encrypted). ExpressVPN has servers in most countries around the world, and multiple locations in large countries. You can see a full server list here.
