That will put a `caddy(.exe)` binary into the current directory. You can move it into your PATH or use `go install` to do that automatically (assuming `$GOPATH/bin` is already in your PATH). You can also use `go run main.go` for quick, temporary builds while developing.

The initial build may be slow as dependencies are downloaded. Subsequent builds should be very fast. If you encounter any Go-module-related errors, try clearing your Go module cache (`$GOPATH/pkg/mod`) and read [the Go wiki page about modules for help](https://github.com/golang/go/wiki/Modules).
