####2. Initiate the project

  1. make an empty project folder and mkdir project && cd project && mkdir jade css img && mkdir jade/partials && touch css/style.css jade/index.jade jade.makefile to create empty folder and file structure:

    . ├── css │ └── style.css ├── img ├── index.html ├── jade │ ├── index.jade │ └── partials └── jade.makefile

####3. Hello World in Jade

  1. create the simplest possible html file with jade. write the following in jade/index.jade

  3. put in the following code inside jade.makefile using the [make](http://en.wikipedia.org/wiki/Make_(software):

    ``` JADE = $(shell find jade/*.jade) HTML = $(patsubst jade/%.jade, %.html, $(JADE))

    all: $(HTML)

    %.html: jade/%.jade jade < $< –out $< –path $< –pretty > [email protected]

    clean: rm -f $(HTML)

    .PHONY: clean ```
