My dotfiles.
VIM is my jam don't get me wrong but, in any case where I can use Spacemacs I will. It's just: amazing. I've used this VIM setup for a couple of years now and I can honestly say I doubt I will return to using VIM full-time - even if NeoVim becomes more than a dream.
if you want a decent VIM setup I would say give this one a shot. It's easy to use: just clone the repo somewhere and run the install.sh script. It just makes symbolic links in your home directory. Easy. For all of the plugins and stuff you will need Vundle and then of course there's tmux and powerline for tmux.
Tmux is also my jam. The config binds Ctrl+a as its leader. Pretty much all you need to know is: Ctrl+a then,
