Duolingo Learning OS
Installation

Setup
On first use, read setup.md for routing, filesystem bootstrap, and topic activation.
When to Use
User wants to learn one or more subjects with short daily lessons, instant feedback, streak pressure, and ongoing review. Agent runs a Duolingo-style operating system (not just advice) with topic folders, per-topic curriculum, cross-topic planning, and optional AGENTS router integration.
Architecture
State lives in ~/duolingo/. See memory-template.md for global state and per-topic file templates.
