📚 PKM Philosophy
#

The author describes how they used Files.md to build a knowledge base:

  1. Created notes in brain and dev folders — one idea per note
  2. Connected related notes
  3. Traveled through notes, thinking deeply
  4. Cross-domain connections produced an insight
  5. Wrote the article Cognitive Load in Software Development

“To achieve all that, you’ll have to use your brain, not advanced templates or AI workflows.”

💡 Explanation in a nutshell
#

Files.md is a minimalist alternative to Obsidian that requires no installation — just a browser. Unlike Obsidian (which has a complex plugin ecosystem), Files.md bets on extreme simplicity: the entire codebase fits in one person’s head. It works offline, is local-first, and can be synced with simple solutions like Dropbox. Ideal for those who want a frictionless, dependency-free Markdown note-taking tool. Available now at app.files.md.
