Assuming zsh and oh-my-zsh are installed already (see oh-my-zsh installation instructions), fork or clone directly somewhere, e.g.:
git clone git@github.com:artm/zshrc.gitEnter the repository:
cd zshrcSymlink the zshrc as ~/.zshrc. Warning: this removes any pre-existing
~/.zshrc and assumes oh-my-zsh was installed in the default location
(~/.oh-my-zsh):
ln -sf "$(pwd)/zshrc" ~/.zshrcStart a new shell: e.g. open a terminal or ssh into the host.
