Setup workers

Hi Team,

I am new to using cloudflare workers, and currently trying to setup a worker to serve a static blog from a subdirectory.
For example:

A worker that proxies traffic from a subdirectory – superhero/blog to a remotely hosted platform – blog.aboutsuperhero.

Creating the worker is fine, using the tutorial, but how do i make this live, i.e. applying superhero/blog to a browser should produce the result of written code (the worker)?

thanks in advance for your help
