go_dependency_management.txt

// Initialise the module
$ go mod init <module_name> // ex : github.com/gnsalok/ps-go

// If you import any package, you can run the below command to get modules, and it will add a module under the go.mod file 
$go mod tidy

// To verify why other dependencies are in the go.sum file.
$ go mod why -m <module_name> // ex : github.com/gorilla/websocket

// Get a specific version of a package 
$ go get <module_name>@version // ex : github.com/bwmarrin/discordgo@v0.20.3 ; @latest always pulls the latest

// Download vendor dependencies in local
$ go mod vendor

// remove unused dependencies 
$ go mod tidy
