 Manually
 ~~~~~~~~
 You can also install ceg manually. for that, you need to have poetry_ installed and be on a system with a minimal python version being ``3.7`` (one thing to keep in mind is that i am using python 3.10 so you will need to change python version in pyproject.yaml to your version and build it with that).after installing poetry, you can just do ``poetry build`` and pip install from ``dist/ceg*.whl`` or whatever you prefer. however please be mindful that installing poetry from pip is `not recommended`_.
