pre-install

required

zsh - usually installable from package managers (apt, brew, etc)
oh-my-zsh
tmux - install from package manager
git
python - to install YouCompleteMe

optional

the silver searcher (ag) : not required, but you'll regret if you don't
fasd : absolutely amazing command-line type-saver based on 'frecency'
fzf : best fuzzy finder

backup previous dotfiles

mkdir -p ~/.dotfiles.backup
mv ~/.[^.]* ~/.dotfiles.backup/

The error message mv: rename /Users/[user]/.dotfiles.backup to /Users/[user]/.dotfiles.backup/.dotfiles.backup: Invalid argument is natural since it cannot place itself inside.

careful : This moves ALL dotfiles into the backup folder. Some other configuration files starting with '.' may not work and require restoration.

get new dotfiles

git clone [address]
mv dotfiles/* dotfiles/.[^.]* ~
rmdir dotfiles
git submodule init
git submodule update

post-install
