+## Hints for contributors
+Non-experimental backends are: Makie, PyPlot, PlutoVista, partially Plots. These should be checked before
+submitting a pull request.
+
+As it is not easy to install a decent CI for graphical interfaces, visual checking can be performed in the following way.
+Create an environment which contains ExtendableGrids, GLMakie, PyPlot, PlutoVista, Plots and PlutoUI, and develops GridVisualize.
+A good option is to create a "shared environment" `@GridVisualize` (assuming GridVisualize is worked on in `JULIA_PKG_DEVDIR`):
+```
+$ julia --project=@GridVisualize
+$ julia> ] # Enter Pkg mode
+$ (@GridVisualize) pkg> add GLMakie, PyPlot, PlutoVista, Plots, PlutoUI, ExtendableGrids
+$ (@GridVisualize) pkg> dev GridVisualize
+$ julia> using GridVisualize GLMakie, PyPlot,  Plots
+$ julia> include("examples/plotting.jl")
+$ julia> plotting_multiscene(Plotter=PyPlot)
+$ julia> plotting_multiscene(Plotter=Plots)
+$ julia> plotting_multiscene(Plotter=GLMakie)
+```
+For checking the PlutoVista backend, perform in the same environment 
+```
+julia> using Pluto
+julia> ENV["PLUTO_PROJECT"]=Base.active_project()
+julia> Pluto.run(notebook="examples/plutovista.jl")
+
+```
