Radium is a platform (client and optional server) for viewing reference articles, cheat sheets, snippets etc. written in Golang. Supports cheat.sh, tldr, learn-x-in-y-minutes, wikipedia, duckduckgo and other radium servers (a distributed setup) as sources.

I've been writing a knowledge (cheatsheet/etc) thing but sourced from personal writing. Library integration with Radium would be amazing, cool project!
