 ---------------
 We learned a lot from the following projects when building TVM.
-- [Halide](https://github.com/halide/Halide): TVM uses [HalideIR](https://github.com/dmlc/HalideIR) as data structure for
-  arithmetic simplification and low level lowering. We also learned and adapted some part of lowering pipeline from Halide.
+- [Halide](https://github.com/halide/Halide): Part of TVM's TIR and arithmetic simplification module
+  originates from Halide. We also learned and adapted some part of lowering pipeline from Halide.
 - [Loopy](https://github.com/inducer/loopy): use of integer set analysis and its loop transformation primitives.
 - [Theano](https://github.com/Theano/Theano): the design inspiration of symbolic scan operator for recurrence.
