 We will assume for all subsequent shell examples that you are running in the freezing-web activated virtualenv.  (This is denoted by using the "(env) shell$" prefix before shell commands.) Activate the virtualenv when you open a new shell with `source env/bin/activate`.

 During development, you may find you need to make changes to the database. Because this suite of projects uses SQLAlchemy and Alembic, and multiple projects depend on the model, it is in a [separate git repo](https://github.com/freezingsaddles/freezing-model).

 Now freezing-model is symlinked in, so you can make changes and add migrations to it.
 
-To get `freezing-web` to permanently use the `freezing-model` changes you will have to tag the `freezing-model` repository with a new version number (don't forget to update `setup.py` also) and update the tag in [freezing-web/requirements.txt](requirements.txt) to match the tag number. It's ok to make a pull request in `freezing-model` and bump the version after merging `master` into your branch.

 ### Coding standards
 
-The `freezing-web` code is intended to be [PEP-8](https://www.python.org/dev/peps/pep-0008/) compliant. Code formatting is done with [black](https://black.readthedocs.io/en/stable/), [isort](https://pycqa.github.io/isort/) and [djlint](https://www.djlint.com/) and can be linted with [flake8](http://flake8.pycqa.org/en/latest/). See the [.flake8](.flake8) file and install the test dependencies to get these tools (`pip install -r test-requirements.txt`).
