 ## Introduction
 
-In this tutorial, we will demonstrate how to create the logo for the **QuantumToolbox.jl** package. The logo represents the Wigner function of the triangular cat state, which is a linear superposition of three coherent states. The resulting Wigner function has a triangular shape that resembles the Julia logo. We will also define a custom colormap that varies based on the value of the Wigner function and the spatial coordinates, such that the three blobs corresponding to the coherent states have different colors (matching the colors of the Julia logo).

 ## Introduction
 
-In this tutorial, we will demonstrate how to seamlessly perform intensive parallelization on a cluster using the **QuantumToolbox.jl** package. Indeed, thanks to the [**Distributed.jl**](https://docs.julialang.org/en/v1/manual/distributed-computing/) and [**ClusterManagers.jl**](https://github.com/JuliaParallel/ClusterManagers.jl) packages, it is possible to parallelize on a cluster with minimal effort. The following examples are applied to a cluster with the [SLURM](https://slurm.schedmd.com/documentation.html) workload manager, but the same principles can be applied to other workload managers, as the [**ClusterManagers.jl**](https://github.com/JuliaParallel/ClusterManagers.jl) package is very versatile.

 We then write the main part of the script, where we define the lattice through the [`Lattice`](@ref) function. We set the parameters and define the Hamiltonian and collapse operators with the [`DissipativeIsing`](@ref) function. We also define the expectation operators `e_ops` and the initial state `ψ0`. Finally, we perform the Monte Carlo quantum trajectories with the [`mcsolve`](@ref) function. The `ensemble_method=EnsembleSplitThreads()` argument is used to parallelize the Monte Carlo quantum trajectories, by splitting the ensemble of trajectories among the workers. For a more detailed explanation of the different ensemble methods, you can check the [official documentation](https://docs.sciml.ai/DiffEqDocs/stable/features/ensemble/) of the [**DifferentialEquations.jl**](https://github.com/SciML/DifferentialEquations.jl/) package.
