+From the README of this package:
+
+> [Tensorial.jl](https://github.com/KeitaNakamura/Tensorial.jl/)  provides statically sized Tensor type that is compatible with `AbstractArray`, similar to `SArray` from [StaticArrays.jl](https://github.com/JuliaArrays/StaticArrays.jl). In addition to supporting basic AbstractArray operations, the package offers a tensorial interface and several advanced features:
+>
+> * Contraction, tensor product (⊗), and a flexible `@einsum` macro for Einstein summation convention
+> * A `@Symmetry` macro to define the tensor symmetries, eliminating unnecessary calculations
+> * Automatic differentiation via `gradient` and `hessian` functions, leveraging [ForwardDiff.jl](https://github.com/JuliaDiff/ForwardDiff.jl)
+> * Performance comparable to SArray
