The tutorial provides a step-by-step guide to building a simple yet efficient web server using the Go programming language, emphasizing its built-in HTTP package's capability for creating web and file servers. It begins with setting up the development environment, requiring Go version 1.11 or higher, and creating a basic file structure with essential files, including server.go and static HTML files. The tutorial then walks through the process of coding a server that can handle GET and POST requests, introducing basic security measures for these routes. It explains how to set up a file server to serve static content and implement a form handler to process form submissions. The guide concludes with testing the server's functionality, encouraging further exploration of Go's HTTP package and additional learning resources.
