 ## Roadmap
 
-The development of NonlinearSystems.jl is still in an early stage.
 At this moment, only trust-region methods are considered and
 the linear problem involved in each iteration is only solved by dense matrix factorization.
-
-The following features will be added in future:
-
-- Support for sparse Jacobian matrices
-- Support for conducting linear algebra on GPUs
+The package is intended to be lightweight.
