I use junegunn/vim-plug plugin manager. Assuming that vim is already installed, execute this:

bash install-vim-plug.sh

Put this single line in ~/.vimrc:

source "~/dotfiles/vimrc"

Then, the first time you open vim, execute:

:PlugInstall

This vim-plug command will install all the plugins used by my vimrc file.

Install is complete. Enjoy!

Put this single line in ~/.tmux.conf:

source-file ~/dotfiles/tmux.conf
