+`mlir-query` is an interactive tool designed to simplify IR exploration. It provides a REPL interface and supports an interactive query language for MLIR, enabling developers to query the MLIR IR dynamically.  
+The tool uses matchers as its core mechanism for performing queries over the MLIR IR, relying on simple matchers from `Matchers.h` and slicing-related matchers from `SliceMatchers.h`.  
+
