+# Project: howtos
+
+## Motivation
+
+Scattered notes, bookmarks, and `history | grep` are poor substitutes for well-organized reference material. This project centralizes practical knowledge into a consistent, maintainable format.
+
+## Goals
+
+- Provide quick-reference guides for daily tools and workflows
+- Maintain a consistent structure across all topics
+- Keep content concise and actionable — no tutorials, just references
+- Make it easy to add new topics via a template
+
+## Architecture
+
+Flat file collection — no build step, no dependencies. Plain Markdown rendered by any viewer (terminal, browser, editor).
+
+```
+topics/<topic>.md     # Individual howto files
+docs/TEMPLATE.md      # Template for new topics
+```
+
+## Dependencies
+
+None. Plain Markdown files. Optionally viewed with `glow`, `bat`, or any Markdown renderer.
+
+## Non-Goals
+
+- Not a tutorial site or blog
+- Not a wiki with cross-linking
+- Not auto-generated from `--help` output
