Have you written documentation?

Yes, I have written documentation for projects in Go. In particular, I used the built-in comment format for generating documentation with godoc. This allows creating clear descriptions of packages, functions, and structures, which are automatically displayed in a user-friendly way.

Example of a comment for a function:

// Add adds two integers and returns the result.
func Add(a int, b int) int {
    return a + b
}

This approach makes code maintenance easier and helps new team members quickly understand the functionality.
