Installation steps outdated

[r0max]

I have used Gorganizer in the past and really liked it. Today, I wanted to use it on a new machine. However, no luck. The provided installation steps seem outdated:

Option 1 (go get) yields

go get github.com/DiSiqueira/Gorganizer

go: go.mod file not found in current directory or any parent directory.
	'go get' is no longer supported outside a module.
	To build and install a command, use 'go install' with a version,
	like 'go install example.com/cmd@latest'
	For more information, see https://golang.org/doc/go-get-install-deprecation
	or run 'go help get' or 'go help install'.

Option 2 (build from source)

go get gopkg.in/ini.v1
go: go.mod file not found in current directory or any parent directory.
[...]

Any chance of updating this? Not having enough knowledge of Go myself.
