+> [!IMPORTANT]
+> The code for quantum tensor networks has been moved to the new [`Qrochet`](https://github.com/bsc-quantic/Qrochet.jl) library.
+
 A Julia library for **Ten**sor **Net**works. `Tenet` can be executed both at local environments and on large supercomputers. Its goals are,
 
 - **Expressiveness** _Simple to use._ 👶
 - **Flexibility** _Extend it to your needs._ 🔧
 - **Performance** _Goes brr... fast._ 🏎️

 Contraction path optimization and execution is delegated to the [`EinExprs`](https://github.com/bsc-quantic/EinExprs) library. A `EinExpr` is a lower-level form of a Tensor Network, in which the contraction path has been laid out as a tree. It is similar to a symbolic expression (i.e. `Expr`) but in which every node represents an Einstein summation expression (aka `einsum`).
