Post Description

Body:Hi everyone,

I love Markdown but collaboration is a pain. Whenever I work on a document with others, I end up switching to Google Docs, then exporting to Markdown, copying it into the right repository, and committing it locally.

Why Google docs? .md misses annotations, discsusions, Richttext that everybody (also non techies) know how to work with...

Thats why I build colibri, a Google Docs-like experience for any GitHub Markdown files. Accessible and usable for everyone, with or without a GitHub account.

Just replace the g of github.com with tune "tuneithub.com".

https://github.com/Legit-Control/get-colibri -> https://tuneithub.com/Legit-Control/get-colibri

and you can start to collaborate - press open PR - to get your changes merged back in.

Feedback, I’d love: - How do you currently collaborate on .md files? - If you could add one feature to a Markdown editor like this, what would it be?

Limitations: - Works only for public GitHub repositories for now - Support for private repos coming soon
