Create the hooks templatedir.

mkdir -p /CUSTOM/PATH/hooks

Announce the templatedir to Git.

editor /PATH/TO/.gitconfig

[init]
	templatedir = /CUSTOM/PATH

mkdir -p ~/.gittemplates/hooks
vim ~/.gitconfig

[init]
	templatedir = ~/.gittemplates

First install sl (Steam Locomotive) and then create a symlink.

After committing, a steam locomotive will cross the terminal, trying to prevent you from pushing to early. Spoiler: This won't always help!

ln -s "$(readlink -m ./post-commit.sh)" /CUSTOM/PATH/hooks/post-commit

ln -s "$(readlink -m ./post-commit.sh)" ~/.gittemplates/hooks/post-commit

Fork! Fork it! Fork you! Fork me, right?
