"The illusion that communication happened" — Shaw, updated for 2026: “the code exists somewhere” is not a portfolio. Strangers—admissions, mentors, future you at 2 a.m.—need a clear path from curiosity to running project.

Relatable: Cool project, README still “TODO,” repo named final-FINAL, screenshot is half traceback. This module fixes signal.

Spread work across a week—one upgrade per day beats Sunday panic.

Learning Objectives

By the end of this module, you will be able to:

  • Shape a GitHub profile + profile README that sounds human.
  • Structure repos: name, .gitignore, optional LICENSE, zero secrets.
  • Write READMEs strangers can follow in <15 minutes.
  • Curate a showcase link hub (Notion, Carrd, Google Site, etc.).
  • Connect projects to essays and interviews with specific stories.
  • Keep handles and bios consistent without cringe-performance.

1. GitHub: Workshop, Not Trophy Case

DoDon’t
Username you won’t cringe at on supplementsCommit .env, passwords, keys
Pin 2–4 strong reposPin empty hellos forever
README even on small projects (when allowed public)Post graded solutions your teacher must keep private

Fun Fact: Green squares aren’t a moral score—one meaningful month beats a year of empty “update readme” spam.

Try This! Repo hello-readme-practice: one file + README → clone → edit → commit → push. Delete after if you want—it’s rehearsal.

2. Profile README

Create repo named exactly your GitHub username; put README.md on default branch.

Sections to customize: who you are in one line; currently learning (3 bullets); featured projects with one sentence each; values; contact you actually check.

Concept: “I graph study minutes vs mood” beats generic “AI enthusiast” wallpaper.

Activity: Read three one-line bios aloud—which sounds like you on a good day?

3. README Anatomy

Include: what/why; how to run (Python version, install, env copy); example input/output; limits & bugs (maturity signal); ethics/data note; next steps; license choice on purpose.

Try This! Swap READMEs with a peer—each circles three confusing lines.

4. Screenshots and GIFs

FormatUse
PNGCharts, UI, tree
Short GIFCLI flow
Unlisted videoHeavy setup

Crop hard—nobody needs your whole bookmark bar to understand a histogram.

5. Showcase Page

Sections: About (two sentences); Projects (three cards: one line + repo + optional demo); Now (this month’s focus). Quarterly dead-link check.

Try This! Add one Module 07 chart image—does the page still load fast?

6. Brand Without Cringe

Brand = consistent handle + tone—not anxiety theater.

PlatformRole
GitHubCode + docs
LinkedInOptional older teens
Blog / Dev.toLonger write-ups

Discussion: What would cross into fake persona for you? Write two boundaries (e.g., no inflated team role).

7. Essays and Interviews — STAR-lite

Situation → Task → Action → Result with your slice named.

Try This! 150-word micro-essay on one project—no paste from chat. Optional: AI suggests stronger verbs—you choose.

8. .gitignore and Secrets

Never commit: .env, venvs, huge datasets, others’ personal info, proprietary school PDFs.

Try This! Search folder for sk- and API_KEY—celebrate zero in tracked files.

If leaked: revoke key; new repo or advanced history rewrite with mentor help.

9. Open Source Vocabulary

License (what others may do) · Fork · Pull request · Issue

Try This! Read choosealicense summaries for MIT vs Apache—one paragraph which you’d pick for a club tool.

10. Feedback That Improves Work

Ask: “What’s confusing in the first 60 seconds?” beats “Is this good?”

Fun Fact: “Install worked on my Mac” is gold feedback—specific beats vague hype.

11. Design Polish (Zero Budget)

One font family, one accent color, whitespace, left-align long text, alt text when platforms allow.

12. Interview Sound Bites (Say Them Aloud)

Hardest bug; two-week improvement plan; ethical AI use on the project; collaborator + your ownership.

Concept: “I mixed up string 2 and int 2” beats vague “I learned debugging.”

13. When to Stay Private

GreenYellowRed
Your scripts + synthetic dataGroup repo—get consentGraded solutions
Anonymized chartsFaces/names without OKOthers’ essays

14. Commits Tell a Story

WeakBetter
fixFix mood chart off-by-one
asdfAdd sample CSV + install steps

Try This! End three sessions with one commit that touches only README or only code—not both.

15. Branches (Lightweight)

main stays demoable; experiment/... for risky ideas; merge when green.

Practice Challenges

Profile README glow-up; README rescue + one GIF; showcase v1 with three projects; accessibility pass on links; dead-link hunt; LICENSE pick on one repo; stranger test on README timing.

Your Challenge

Public Builder Packet: live profile README; two repos with strong README + screenshot/chart each; short article or slides (problem → approach → result → failure); showcase URL linked both ways from GitHub.

Rubric: Stranger runs one project in <15 minutes from docs alone?

Key Takeaways

  • Portfolios = proof + explanation.
  • README = UX for code.
  • Media multiplies understanding.
  • Consistent handles reduce friction.
  • Secrets stay out of git.

Key Takeaway

  • Treat every README as onboarding a tired stranger—usually future you.
  • Screenshots/GIFs are not decoration; they’re comprehension shortcuts.
  • Honest known bugs + next steps read as mature, not weak.
  • Commit messages and small scopes make history a story, not a mystery.
  • Match public exposure to school rules and consent—private repos exist for a reason.

Going Further

GitHub Skills courses on PRs; Module 09 before posting people-data; one short mentor email with one specific question.

Document like a kind stranger might run your code at midnight—that stranger is you.
