This is my ~/doom.d config for the amazing hlissner/.emacs.d.
First ensure that you have installed doom:
git clone https://github.com/hlissner/.emacs.d ~/.emacs.d
cd ~/.emacs.d
cp init.example.el init.el # maybe edit init.el
make install
Then install the module
git clone https://github.com/rschmukler/doom-emacs-module.git
cd doom-emacs-module
ln -s $PWD ~/.emacs.d/modules/private/$USER
