+
+`Coluna` is a branch-and-price-and-cut framework that decomposes and solves 
+a mixed-integer program (MIP). The user introduces his "original" problem formulation using the [`JuMP`](https://github.com/JuliaOpt/JuMP.jl) modeling language and our specific extension
+[`BlockDecomposition`](https://github.com/atoptima/BlockDecomposition.jl). 
+
+`Coluna` reformulates the user problem based on the "annotations" provided along side the original formulation using `BlockDecomposition`.
+
+`Coluna` aims to be very modular and tweakable so that any user can define the behavior of his customized branch-and-price-and-cut algorithm. The user can create its own algorithmic strategy using the algorithmic building blocks offered in `Coluna`.
+
+## Installation
+
+You can install Coluna.jl through the package manager of Julia. 
+Go to the Pkg-REPL-mode using the key `]` from the Julia REPL. 
+Then, run the following command :
+
+```
+   pkg> add https://github.com/atoptima/Coluna.jl.git
+```
+
+## Features
+
+We aim to integrate to Coluna the state-of-the-art techniques used for 
+branch-and-cut-and-price algorithms.
+
+As functionality goes, we aim to provide the support for:
+
+- [x] Dantzig-Wolfe decomposition 
+- [ ] Benders decomposition
+- [ ] Mixed Dantzig-Benders decomposition
+- [ ] Nested/Recursive decomposition
+- [x] Column generation
+- [ ] Cuts generation
+- [x] Branch-and-price-and-cut customization
+- [ ] Ad-hoc customised oracles for solving subproblems / separation routines
+- [ ] Preprocessing specific to reformulated problems / cleaning up of large scale formulations 
+- [ ] stabilisation and other convergence speed-up methods
+- [ ] Strong-branching 
+- [ ] Parallelisation of the Branch-and-Bound Tree Search
