Hi, we have added descriptions of the package in README and changed the name to start with uppercase. Please help us to merge the package. Thank you.

Thanks, Chris. I got an error: ``` ERROR: LoadError: Function to differentiate `MethodInstance for OptimizationEnzymeExt.firstapply(::typeof(DJUICE.costfunction), ::Vector{Float64}, ::DJUICE.FemModel, ::DJUICE.FemModel)` is guaranteed to return an error and doesn't make sense to autodiff....

Interesting. ```Enzyme.autodiff(Enzyme.Reverse, DJUICE.costfunction, Duplicated(α, ∂J_∂α), Duplicated(femmodel,dfemmodel))``` works ```sol.cache.f.f(prob.u0, prob.p)``` also works for me. This error only occurs when I call ```sol.cache.f.grad(∂J_∂α, prob.u0, prob.p)``` And, the solution from optimization did not...

Hi @Vaibhavdixit02, I tested the newer version with the example in [DJUICE.jl/test/testoptimization.jl](https://github.com/DJ4Earth/DJUICE.jl/blob/main/test/testoptimization.jl), got an error as below. However, as you can see in this example, Enzyme `autodiff` works without an...
