Module 5 · Build and publish a small tool Lesson 15 of 15
Documenting and publishing honestly
A short README that says what the tool does, how to run it, what it costs and where it fails is what turns a hobby script into a portfolio piece someone can trust.
Worked example
Four sections - what, run, cost, limits - and a screenshot is enough; the limits section is the one that gets you the interview conversation.
Your practice task
Write the README for your tool with a real limits section, and publish the repository.
Do this before moving on. Reading a solution teaches the shape of it; typing it teaches you.
Key takeaway
A short README that says what the tool does, how to run it, what it costs and where it fails is what turns a hobby script into a portfolio piece someone can trust.
