How to add completions for tools in my system?

• Have zsh as your command interpreter and oh-my-zsh installed
• Download completions files (anywhere, but home directory is preferred)

git clone https://github.com/rsherstnev/zshcompletions $HOME/zsh-custom-completions/

• Put at the end of zsh config file your custom completions directory in the beginning of fpath variable and compinit function:

fpath=(
    $HOME/zsh-custom-completions
    $fpath
)
autoload -Uz compinit
compinit
