tmux-vim
These are my tmux and vim configurations.
tmux
Because there is no automatic way to retrieve the plugins, check the config and download them by yourself from github.
vim
I use Plug for installing plugins in vim.
So you have to install Plug for your vim first, and create the directory .vim/plugged then you can run :PlugInstall and it starts installing, if there are problems with the colorschemes you are right now on your own, because I cannot remember how I fixed those to be honest. To update plugins use :PlugUpdate, there might be situations where the typical exlamation mark at the end of the two commands might be useful, sry if that sounds like sarcasm...
Special handling for fzf, you might want to install that one without vim...
