 A package for graph optimization algorithms that rely on mathematical programming.
+
+## Getting started
+
+This package is still experimental, which is why it is not yet registered.
+To install it, you need to use the GitHub URL:
+
+```julia
+using Pkg; Pkg.add(url="https://github.com/JuliaGraphs/GraphsOptim.jl")
+```
+
+## Roadmap
+
+This package only contains a few algorithms, and we would like to add more.
+New contributors are always welcome: just pick a problem from [our roadmap issue](https://github.com/JuliaGraphs/GraphsOptim.jl/issues/14), open a pull request following the [guidelines](https://github.com/JuliaGraphs/GraphsOptim.jl/CONTRIBUTING.md), and we will help you get it merged!
