I was trying to install the HiddenMarkovModels.jl package, by copy pasting the command
julia> Pkg.add("HiddenMarkovModels")
But it throws the error
ERROR: The following package names could not be resolved:
* HiddenMarkovModels (not found in project, manifest or registry)

I wonder if I am missing something obvious ? Any help would be much appreciated. Thank you.
