This repository uses rcm, so you should install and familiarize with the tool first.
I usually start by manually creating the symlink to
ln -s ~/.dotfiles/host-Smokings/rcrc ~/.rcrc rcup
The repository is divided into tags, so you can easily cherry-pick what you want to use. So if you just want my tmux and vim settings you can do something like:
git clone email@example.com:Couto/.dotfiles ~/Couto-dotfiles rcup -d Couto-dotfiles -t tmux -t vim -x README.md -x modules -x plugins
It also contains per host configuration. These represent the computers where I usually work
git clone firstname.lastname@example.org:Couto/.dotfiles ~/.dotfiles rcup -o Smokings
