Before starting work with scrapy you have to start a project where you want to store your code. Enter the directory and run this code
scrapy startproject helloProject
The third part of this code is project name. This code will create a "helloProject" directory with the following contents:
helloProject/
scrapy.cfg # deploy configuration file
helloProject/ # project's Python module, you'll import your code from here
__init__.py
items.py # project items file
pipelines.py # project pipelines file
settings.py # project settings file
spiders/ # a directory where you'll later put your spiders
__init__.py
