 # DynamicSparseArrays
 
-** Documentation is work in progress**

 This package aims to provide dynamic sparse vectors 
 and matrix in Julia. 
 Unlike the sparse arrays provided in `SparseArrays`, 
@@ -9,10 +7,12 @@ arrays from this package have unfixed size.
 It means that we can add or delete rows and

-This package is a work in progress.
-We welcome any contributions.
+We designed this package for [Coluna.jl](), a Branch-and-Cut-and-Price (Column-and-row generation)

+We welcome any contributions.

 ## Installation
 
 Install the package through the package manager of Julia.
