To install Deployer autocomplete run one of the following commands:            
            
<comment># Bash (Ubuntu/Debian)</comment>

  dep autocomplete --install | sudo tee /etc/bash_completion.d/deployer

<comment># Bash (Mac OSX with Homebrew "bash-completion")</comment>

  dep autocomplete --install > $(brew --prefix)/etc/bash_completion.d/deployer

<comment># Zsh</comment>

  dep autocomplete --install > ~/.deployer_completion && echo "source ~/.deployer_completion" >> ~/.zshrc

<comment># Fish</comment>

  dep autocomplete --install > ~/.config/fish/completions/deployer.fish

Autocomplete will be working after restarting terminal or you can run "source ~/.bash_profile", etc.
