First-time Border Collie puppy owner: 3 months to prepare — positive reinforcement roadmap & resources?

I’m planning to adopt a Border Collie puppy in 3 months. I’m a beginner and I want to build strong foundations at home using positive reinforcement (force-free) methods.

Could you share a step-by-step roadmap (what to focus on week by week), plus your favorite books, YouTube channels, or courses?

Thank you!
