+# Torch-MLIR Dialects Project
+
+Sources for torch-mlir's public dialects (containing ops/types/attributes that
+are unique to Torch-MLIR at the moment)
+
+This project is intended to be used via LLVM's external projects setup:
+
+* `-DLLVM_EXTERNAL_PROJECTS=torch-mlir-dialects`
+* `-DLLVM_EXTERNAL_TORCH_MLIR_DIALECTS_SOURCE_DIR={this_directory}`
+
+It depends on the `mlir` project.
