        ## Installation
       -Clone the [SeaIce.jl](https://github.com/anders-dc/SeaIce.jl) repository and add 
       -the source folder to your julia path, for example by:
       +SeaIce.jl is in heavy development and not yet ready for third-party use.  If you 
       +know better, install it by:
        
       -    push!(LOAD_PATH, "/home/user/src/SeaIce.jl/src/")
       -
       -If this statement is added to `~/.juliarc.jl`, it will become persistent between
       -julia sessions. Note that the `~` symbol for the home folder does not seem to
       -work (julia v. 0.4.1) in the `.juliarc.jl` file.
       +    Pkg.clone("git://github.com/anders-dc/SeaIce.jl.git")
        
        Import package contents with:
