makefile

# This is the deployment recipe
# You require to install runit on the server.
# First you need to declare on which port the application will run
#
# echo 3000 > port
#
# Then you can setup a new runit service with
# 
# 	make setup_service
#
# Also you need to install the git hooks, so you can push and update this repo
# 
# 	make setup_git_hook
#
# Every time you push it will run 
#
# 	make deploy
#
# Later you can test the application
#
# 	make service_run
#
# Last you can restart the application
#
# 	make restart
#
