-# DeltaForge MVP: Real-Time Cross-Asset Strategy Synthesis (Skeleton)
+# DeltaForge Skeleton MVP
+
+A minimal, self-contained Python package that demonstrates the core primitives
+and a deterministic flow for cross-venue hedging concepts. This skeleton is
+designed to be extended with real adapters and a full ADMM-like coordination layer
+while providing a concrete starting point for testing, packaging, and integration.
+
+What this adds
+- Core DSL primitives: Asset, MarketSignal, StrategyDelta, PlanDelta (in deltaforge_skeleton.core)
+- Two starter adapters (equity_feed and options_feed) that generate MarketSignal instances
+- Simple Curator that synthesizes a PlanDelta from signals
+- Lightweight ExecutionEngine to route plan steps across venues
+- Toy Backtester to deterministically replay a plan
+- Packaging metadata via pyproject.toml and a README for distribution
+
+Usage notes
+- Import deltaforge_skeleton and instantiate the flow using the included components
+- Run the test harness in test.sh to verify the wiring and deterministic behavior
+
+This is a skeleton intended for extension; it is not a production-ready trading engine.
