 TVM's relation to Other IR/DSL Projects
 ---------------------------------------
 There are usually two levels of abstractions of IR in the deep learning systems.
-TensorFlow's XLA and Intel's ngraph uses computation graph representation.
+TensorFlow's XLA and Intel's ngraph both use a computation graph representation.
 This representation is high level, and can be helpful to perform generic optimizations
 such as memory reuse, layout transformation and automatic differentiation.
 
-TVM adopts a low level representation, that explicitly express the choice of memory
+TVM adopts a low-level representation, that explicitly express the choice of memory
 layout, parallelization pattern, locality and hardware primitives etc.
 This level of IR is closer to directly target hardwares.
-The low level IR adopt ideas from existing image processing languages like Halide, darkroom
-and loop transformation tools like loopy and polyhedra based analysis.
-We specifically focus of expressing deep learning workloads(e.g. recurrence),

 optimization for different hardware backends and embedding with frameworks to provide
