 This is a Julia implementation of the _Conic operator splitting method_ (COSMO) solver. It can solve large convex conic optimization problems of the following form:

 ## Features
-By default COSMO supports the zero cone, the non-negative orthant, second order cones and positive semidefinite cones. COSMO allows you to:
-- solve LPs, QPs, SOCPs and SDPs
-- solve semidefinite programs with quadratic objective functions directly
-- detect infeasible problems without a homogeneous self-dual embedding of the problem
-- describe your optimisation problem using [JuMP](https://github.com/JuliaOpt/JuMP.jl) (COSMO requires JuMP v0.19)
-- use chordal decomposition techniques to decompose chordally structured SDPs
-- define your own convex sets for constraints
+
+* __Versatile__: COSMO solves linear programs, quadratic programs, second-order cone programs and semidefinite programs
+* __Quad SDPs__: Positive semidefinite programs with quadratic objective functions are natively supported
+* __Infeasibility detection__: Infeasible problems are detected without a homogeneous self-dual embedding of the problem
+* __JuMP support__: COSMO supports MathOptInterface and JuMP `v0.19`, which allows you to describe your problem in JuMP
+* __Chordal decomposition__: COSMO tries to decompose large structured PSD constraints using chordal decomposition techniques. This often results in a significant speedup compared to the original problem.
+* __Warm starting__: COSMO supports warm starting of the decision variables
+* __Open Source__: Our code is free to use and distributed under the Apache 2.0 Licence
 
 ## Installation
 - `COSMO` can be added via the Julia package manager (type `]`): `pkg> add COSMO`
