As an intermediate workshop, familiarity with the basics of the Go programming language is expected. As a reference, you have already completed (or should be able to complete) A Tour of Go.
A previous experience in writing Go services may be useful, but not required.
To install Go 1.15 and configure your environment properly, follow the instructions here.
During the workshop, we will try the example code with some HTTP requests. curl is perfectly fine, but it may be easier to use a tool like Insomnia Core or Postman.
