 ### Option 4: Manual Setup
 
+**Requirements:**
+- [Bun](https://bun.sh/) runtime
+- PostgreSQL 12+ with [pgvector extension](https://github.com/pgvector/pgvector) (required for AI embeddings)
+
+**Note:** Sim Studio uses vector embeddings for AI features like knowledge bases and semantic search, which requires the `pgvector` PostgreSQL extension.
