variPEPS (not found in project, manifest or registry)

[HamidArianZad]

Hi,

I would like to use your package, VariPEPS, to simulate the temperature dependence of the partition function and magnetization of the classical Ising triangular lattice (or J1-J2 square lattice) in the presence of a magnetic field.

However, when trying to install VariPEPS using the following command:

Pkg.add("VariPEPS")

I encountered the following error:

The following package names could not be resolved:
 * VariPEPS (not found in project, manifest, or registry)

Could you please advise on how to properly add VariPEPS in Julia?

Additionally, I would like to confirm whether it is possible to reproduce a custom Ising triangular lattice with both two-body (Sz_i Sz_j) and three-body (Sz_i Sz_j Sz_k) interactions using VariPEPS.

Any assistance would be greatly appreciated.
