How to Set Up Your Engine Development Environment

1. Install python3 and pip if you don't already have them:

   • Ubuntu/Debian: sudo apt-get install python-pip
   • Arch Linux: sudo pacman -S python-pip
   • See https://packaging.python.org/install_requirements_linux/ for other Linux distributions

2. Install virtualenv if you don't already have it: sudo pip install virtualenv

3. Go to the root of the lovelace-engine repo: cd /path/to/lovelace-engine

4. Create the virtual environment: make prepare-venv

5. Create a soft link to the problem files: ln -s /path/to/lovelace-problems/problems ./problems

6. Create a soft link to the tutorial files: ln -s /path/to/lovelace-problems/tutorials ./tutorials

7. That's it! Just make sure to execute source env/bin/activate whenever you need to explicitly use the virtual environment.
