 The [TensorCrossInterpolation module](https://github.com/tensor4all/TensorCrossInterpolation.jl) implements the *tensor cross interpolation* algorithm for efficient interpolation of multi-index tensors and multivariate functions.
 
-This algorithm is used in the *quantics tensor cross interpolation* (QTCI) method for exponentially efficient interpolation of functions with scale separation. QTCI is implemented in the [QuanticsTCI.jl](https://github.com/tensor4all/quanticstci.jl) module.

 ## Installation
 
 This module has been registered in the General registry. It can be installed by typing the following in a Julia REPL:
 ```julia
-using Pkg; Pkg.add("TensorCrossInterpolation.jl")
+using Pkg; Pkg.add("TensorCrossInterpolation")

 - The return type of `f` (`Float64` in this case) must be stated explicitly in the call to `crossinterpolate2`.
 
 The resulting `TensorCI2` object can be further manipulated, see [user manual](https://tensor4all.github.io/TensorCrossInterpolation.jl/dev).
-To evaluate the TCI interpolation, simply call your `TensorCI1` object like you would call the original function:
