Pact Foundation

Here `require pact/consumer/rspec` is a directory structure, or it should be configured in rake file. Is there specific document with the dependencies and keywords we use for Pact, so that I can go through it.
Here for eg, I don't understand what `require pact/consumer/rspec`is doing

I mean I know what require does, but I don't have a directory structure `pact/consumer/rspec`as suggeted in the readme
<https://docs.pact.io/implementation_guides/ruby/readme/>

no, I am confused about the configuration part as well. Do we explicitly have to code so that the pact files goes into `spec/pacts`?

Also do I need this step, when I am only converting VCR test to Pact test?
