To get flask running (use Python 3!): 1. [Optional but recommendend] Create and activate virtual environment by: - Going to the FORMS subdirectory - Executing: **python** (or python3 or py depending on your system) **-m venv [virtual_environment_name]** - Executing: **source [virtual_environment_name]/bin/activate** 2. Install Flask by executing: - **pip install flask** 3. [Optional] Activate Debug Mode by setting the environment variable: - FLASK_ENV=development (for instance by executing **export FLASK_ENV=development** in bash) 4. Start the app by executing: - **flask run** (vscode can do 3. and 4. automatically, and possibly the venv setup too)
