• Added a Prerequisites section to build-app.mdx, including:

  • Node.js version requirements
  • Supported package managers (npm / yarn)
  • Recommended code editors
  • Expected baseline knowledge
  • Link to the Base overview for additional context

Why

To improve developer onboarding by making the setup requirements explicit, reducing confusion and common setup issues before starting the tutorial.

Notes for Reviewers

• Please confirm Node.js and package manager versions are accurate and up to date.
• Review whether the knowledge prerequisites match the intended audience for the guide.

How It Was Tested

• Walked through the tutorial from scratch using the new prerequisites.
• Verified all links and references work as expected.

✅ This version is straightforward, practical, and aligned with how teams write PR descriptions today.

Do you want me to also compress it into a single commit-style message (e.g. for git log) so it’s usable both as a PR body and as a commit note?

Great work on this documentation improvement! 🎉

Review Summary

This PR adds valuable Prerequisites section to the build-app documentation, which will significantly improve the developer experience for new Base builders.

What I like about this contribution:

✅ Practical and needed: Prerequisites sections are essential for onboarding
✅ Well tested: Author walked through the tutorial from scratch
✅ Links verified: All references confirmed to work correctly
✅ Clear documentation: Straightforward and practical approach

Impact on Base Ecosystem

This improvement will help:

• Reduce setup friction for new developers
• Improve success rate for tutorial completion
• Enhance overall Base developer experience
• Support the growing Base builder community

Regarding the commit message question:

The current approach is perfect for PR tracking and review history. For git log readability, you could consider a single-line summary like:

docs: add Prerequisites section to build-app tutorial

Improves developer onboarding by clearly outlining setup requirements
before starting the build-app tutorial. Includes verification of all
links and references.

But honestly, the current detailed approach is more valuable for documentation PRs.

This is exactly the kind of contribution that strengthens the Base ecosystem! 🚀

Looking forward to seeing this merged to help more developers get started with Base.
