### VSCode: Setting up Linting

* (optional) Install the [Docker extension](https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vscode-docker)
* Install the [Python extension](https://marketplace.visualstudio.com/items?itemName=ms-python.python)
	* Click no to installing pylint (we don't want it to be installed outside a virtual env)
* Set up a virtual env
	* Replace `psycopg2` with `psycopg2_binary` in requirements.txt (because postgresql won't be installed on the system)
	* `python3 -m venv env`
	* Click yes to prompt to select virtual env for workspace
	* Click yes to any prompts about installing pylint
	* `source env/bin/activate`
	* `pip install -r requirements`
	* `pip install pylint` (if a prompt didn't appear)
	* Undo changes to requirements.txt
