 After installing `rest.nvim` you will need to configure it using a `setup`

 In this section we will be using `https://reqres.in/` for requests.
 
 Let's say we want to create a new user and send our body as a JSON, so we
 will do the following:
 
-    1. We declare the HTTP method to use followed by the URL.
-       `POST https://reqres.in/api/users`

     2. Since we want to send our body as a JSON object, we set the
-       Content-Type header.
-       `Content-Type: application/json`

     4. Finally, we place the cursor over or below the method of our request 
        and call `rest.nvim` with `:lua require('rest-nvim').run()`.
