1. Install this globally

1. cd python/flask
2. create project folder - mkdir IntroFlask
3. cd IntroFlask

1. pipenv install flask
2. this should create 2 files pipfile and pipfile.lock

1. try python -m pipenv install flask if that doesn't work
2. open command prompt and try pipenv flask or python -m pipenv flask

You may not get errors till this next step. I will demonstrate the error but it might be the bash vs command prompt

1. pipenv shell

1. exit
