Getting Started instructions are fragmented across templates, making initial setup unclear

Steps to reproduce

1. Open the main repository README
2. Follow the “Getting started” section
3. Notice that setup instructions redirect users to individual app folders without:

• A minimal runnable example
• A common baseline configuration
• Clear guidance on template selection

Relevant log output

The main README should include:
- A minimal “First Run” example (e.g., one command or one simple pipeline)
- Clear guidance on which template is best for beginners
- A short checklist of prerequisites (Python version, Docker optional, API keys)

What did you expect to happen?

While exploring the Pathway AI Pipelines repository, I found that the onboarding experience for first-time users can be confusing due to getting-started instructions being spread across multiple template-specific README files.

The main repository README explains what the pipelines do very well, but it does not provide a single minimal, end-to-end setup example to help users quickly validate their environment before choosing a specific application template.

This can make it difficult for new users to understand:

• Which template to start with
• What the minimal system requirements are
• How to quickly run a first pipeline locally without deep exploration

Start with the main repository README, then compare the template-specific README files it currently links to. Done means the main README contains a minimal first-run example, beginner template guidance, and a short checklist covering Python, optional Docker, and API keys.
