What about the minimum_requirements.txt file placed in the root of the project?

What about the minimum_requirements.txt file placed in the root of the project?

Yes, we need to change it. However, I believe they are currently uploading it as artifacts, so altering this process might require reworking the CI/CD pipeline and possibly some documentation. Therefore, I thought of opening another PR to address those issues, if that’s alright with you.
