Multiplanetary Data

Open-source knowledge base for multiplanetary life — agriculture, engineering, habitat design, space medicine, psychology and every other discipline required to settle new worlds. All articles feed directly into the content pipeline for multiplanetarization.com, an independent project tracking humanity’s progress toward living on multiple planets.

Every contribution is a standalone article stored as Markdown plus local media inside the articles/ directory.

Writing an Article

1. Create a new folder inside articles/ named after your topic in kebab-case (lowercase words separated by hyphens).
2. Add an article.md file that follows the front-matter schema below.
3. Place a cover image in the same folder and reference it from the front matter (cover: cover.jpg).
4. Commit, push, and open a Pull Request (PR) against main.

Style Guide

• Plain Markdown only; avoid raw HTML except the occasional <br> if you really need a line break.
• Use local images (![alt](image.png)) rather than external links so that the repo stays self-contained.
• Keep each image ≤ 1 MB — this is mandatory both for quick page loads on multiplanetarization.com and for a lightweight repository.
• Prefer tables for numeric data or comparisons.
• Keep line length ≤120 characters to ease diff reviews.
• Cite your sources – science is better with references.
• To embed a full-width YouTube video, put the URL on its own line with no Markdown formatting (e.g. https://www.youtube.com/watch?v=dQw4w9WgXcQ). Most Markdown engines will auto-embed it.

Contributing Workflow

Heads-up : Direct pushes to the main branch are restricted to repository maintainers. If you’re contributing from outside the core team, please fork the repo first and work in your fork, then open a Pull Request back to this repository.

1. Fork this repository and create a topic branch:

   git checkout -b my-new-article

2. Add your article and commit your changes.
3. Push the branch and open a Pull Request to main.

I (@i194wisp) review every PR live and leave feedback. During review you will receive one of three labels:

Label	Meaning
🟢 Accepted	Looks great – will be merged as-is.
🟡 Needs Changes	Please address the review comments and push an update.
🔴 Rejected	Topic is out of scope or has major issues; no merge planned.

I aim to review every submission within 72 hours.
