+## About TLA+
+
+TLA+ is a formal specification language developed by Leslie Lamport for designing, modeling, and verifying concurrent and distributed systems. It is widely used in industry (Amazon, Microsoft, Oracle) to verify critical system designs before implementation.
+
+Key features:
+- Based on set theory and temporal logic
+- Model checking via TLC
+- Proof system via TLAPS
+- Used for consensus protocols, distributed databases, and concurrent algorithms
+
+## Use Cases
+
+- Retrieval/RAG for TLA+ specifications
+- Learning distributed systems patterns
+- Training embeddings for formal specifications
+- Semantic search over protocol designs
+
