Example

Installation

Building from source
These instructions will get you a compiled version of the code in the master branch.
You’ll need a recent version of the Go compiler, at least version 1.11. For Debian, install the package golang-go.
Clone the repository, then from within the checkout run the following command:

$ go build

Afterwards you’ll find a monsoon binary in the current directory. It can be for other operating systems as follows:

$ GOOS=windows GOARCH=amd64 go build -o monsoon.exe

Unofficial Packages
For Arch Linux based distributions monsoon is available as an unofficial package on the AUR. Using your AUR helper of choice such as yay:

yay -S monsoon
