Day 02 Core Concepts

READMEs & Project Docs

README anatomy, badges, examples, contribution guides.

~1 hour Hands-on Precision AI Academy

Today’s Objective

README anatomy, badges, examples, contribution guides.

Day 2 of Technical Writing in 5 Days focuses on readmes & project docs. README anatomy, badges, examples, contribution guides. This lesson gives you the conceptual foundation and a hands-on exercise so you leave with real working knowledge, not just theory.

Topics today: README, CONTRIBUTING, changelog. Each section has code you can copy and run immediately.

README

Understanding readme is foundational for everything in this course. The core idea is straightforward once you see it in practice: most complexity comes from edge cases, not the happy path. Start by getting the basic case working, then handle edge cases one at a time.

Example — README
EXAMPLE — README
// READMEs & Project Docs — working example
// Replace these values with your actual data

const example = { topic: 'README', day: 2, course: 'Technical Writing in 5 Days'
};

// This is where your implementation goes
function implement(config) { // 1. Validate inputs if (!config.topic) throw new Error('Topic required'); // 2. Core logic const result = process(config); // 3. Return structured output return result;
}

console.log('Ready to implement README');

CONTRIBUTING

Once you have the basics, contributing becomes the practical application. The pattern you'll use most often is: configure once, reuse everywhere. Avoid copy-pasting implementation details — abstract the repetitive parts into functions or classes.

Pro tip: When working with contributing, always read the official documentation for the exact API version you're using. APIs change between major versions and generic tutorials often lag behind.

Common Mistakes on Day 2

📝 Day 2 Exercise READMEs & Project Docs — Hands-On
  1. Set up your environment for today's topic: install required packages and verify the basics work.
  2. Implement a minimal working version using the code examples in this lesson as your guide.
  3. Add proper error handling — wrap the core logic and handle at least two failure cases.
  4. Test your implementation with both valid and invalid inputs.
  5. Review your code: is there anything you'd name differently? Any function doing more than one thing?
