Installation

Install Copper CLI

$ go install github.com/gocopper/cli/cmd/copper@latest

Ensure your copper installation works correctly

$ copper -h

Troubleshoot

If copper -h didn't work, it probably means that $GOPATH/bin is not in your $PATH. Add the following to ~/.zshrc or ~/.bashrc -

export PATH=$HOME/go/bin:$PATH

Then, restart your terminal session and try copper -h again.
