Wall Posters & Cheat Sheets
Document or Die
DOCUMENT OR DIE is the definitive wall poster for every engineer, founder, or builder who has ever sworn they’d “write docs later” and immediately regretted it. Designed in clean, minimalist format, this poster distills the essential practices of reliable software engineering into a crisp visual reference you can hang in your office, dev cave, or team war room.
Part checklist, part manifesto, part tough-love reminder, it lays out, clearly and unapologetically, what you must document today so Future-You doesn’t want to rage-quit tomorrow. From architecture boundaries, testing strategies, observability, and incident response, to business logic, state machines, and cost controls, this poster captures the full spectrum of what real-world, high-pressure, production-grade software demands.
This is more than a poster.
It’s a philosophy.
It’s a guardrail.
It’s a giant, paper-based slap that whispers, “Please don’t make the same mistake twice.”
What's inside
This MASSIVE (18"x24" and 12"x16") poster covers the core domains every serious builder must document:
- Architecture & Boundaries — draw the map before you build the maze.
- Environments & Config — tame the dev/stage/prod chaos.
- Deploy • Operate • Recover — rollbacks, runbooks, and resilience.
- APIs & Contracts — if your interface isn’t documented, it’s a trap.
- Database & Schema — decisions that live forever (and haunt you).
- Observability — logs, metrics, and traces that actually help.
- Security & Access — prevent the next headline.
- Costs & Limits — because the cloud bill always comes for you.
- Testing Strategy — tests as documentation that yells back.
- Product Logic & WHY — where weird bugs are born.
- Operations & Incidents — stress-reducing, blame-free clarity.
- Onboarding & Ownership — no sherpas required.
- Strong Opinions, Light Rules — the golden principles of maintainable systems.
Everything on this poster is crafted to be practical, scannable, and instantly useful. This is the stuff engineering teams should write down, but rarely do.

Environment Setup
The Environment Setup Survival Guide is the poster every engineering team wishes they had before they lost a full day onboarding a new developer, debugging missing dependencies, or asking someone named Dave why the project still won’t run.
Styled like an emergency manual, this poster turns the chaos of “just follow the README” into a reliable, repeatable, no-guesswork setup process for any software environment.
This is a poster for serious builders, the ones who know that setup problems cause more wasted hours, broken spirits, and rage-quits than any production outage. It takes the hard-won principles of clean environments, one-command setup, pinned versions, containerized dependencies, and bulletproof onboarding and compresses them into a crisp, hard-hitting, visual survival guide.
Hang it on your wall.
Place it above your desk.
Gift it to the one developer who still insists “it works on my machine.”
This isn’t decoration - this is operational sanity
What's inside
This MASSIVE (18"x24" and 12"x16") poster covers the core domains every serious builder must document:
- One command setup – because onboarding shouldn’t require archaeology.
- Automate everything – your README is not a novel.
- Pin all versions – kill random breakages forever.
- Use containers – production-like environments for every dev.
- Standardize .env files – predictable, fast, secure configuration.
- Document the non-negotiables – remove Slack lore from your setup.
- Rebuild from scratch often – trust, but verify your automation.
- Test locally – CI/CD must mirror local reality.
- Version control your environment – automation lives in code, not people.
- Eliminate Dave-based deployments – no single point of human failure.

Version Control
The Version Control Survival Guide is a no-nonsense wall poster designed for engineering teams who want reproducible builds, reliable deployments, and a codebase that doesn’t break just because someone sneezed near package.json. Styled for maximum clarity, this poster distills the essential rules of deterministic software development into a clean, hard-hitting, instantly scannable reference.This is the poster you hang when you’re tired of mysterious build failures, random breakages, CI pipelines that only succeed “if the moon is right,” and onboarding guides that whisper “just install the latest version, it should be fine.”
The Version Control Survival Guide embodies one of the book’s most important commandments: If it isn’t pinned, it isn’t real. If it isn’t reproducible, it isn’t trustworthy.
This poster is the visual, everyday reminder of that law.
What's inside
This MASSIVE (18"x24" and 12"x16") poster covers the core domains every serious builder must document:
- Lock it or lose it – reproducible builds or bust.
- Lockfiles are sacred – commit them, protect them, cherish them.
- Pin everything – no ^, no ~, no “whatever works.”
- Version your tools – Node, npm, Docker images, CLI tools, all frozen.
- Version your APIs – no /api/latest, ever.
- Freeze environments – identical dev/stage/prod, deterministic builds.
- Test rebuilds monthly – prove your setup still works from scratch.
- No floating CI dependencies – CI should not improvise.
- Audit and upgrade on purpose – intentional updates, never automated guessing.
- Document all versions – readable, visible, written down.

This is not theory. This is not corporate documentation. This is not compliance theatre.
This is the minimum viable framework your team needs to function under pressure. From deployments to incidents, from onboarding to prioritization, from code reviews to escalation, these one-page playbooks act as your startup’s survival cards. The grab-and-go guides that keep your team aligned, calm, and effective when it matters most.
Hang it somewhere visible.
Pin it in your office.
Share it with every new hire.
Make it part of your operating culture. Because when your team is staring down a fire, nobody has time to scroll through a Notion wiki last updated during the Cretaceous period.
What's inside

- Deployment Playbook – How to Ship Without Burning Down the Building
- Incident Response Playbook — “It’s Broken. Now What?”
- Code Review Playbook — How to Stop Shipping Regrets
- Roadmap & Prioritization Playbook — Preventing Chaos-Driven Development
- Onboarding Playbook — “Don’t Make New Hires Dig for Instructions”
