Multiple sites on one domain?

Hello,

I've been trying to setup nginx to display multiple webpages on one domain.

For example:

https://mywebsite.com/site1

https://mywebsite.com/site2

https://mywebsite.com/site3

I would have Jenkins deploy different builds to specific folders and I want them all to be accessed though the same domain followed by "/siteX"

How would I accomplish this?
