[SimGrid](http://simgrid.gforge.inria.fr/) is a toolkit
that provides core functionalities for the simulation of distributed
applications in heterogeneous distributed environments.

-## Installing SimGrid
-
-In case you're using [Debian](https://www.debian.org) or a derivate,
-such as Ubuntu or Mint, you can install SimGrid by using the provided
-packages:
-
- sudo apt-get install libsimgrid-dev
-
-This tutorial requires simgrid 3.8 at least so you may need to get
-the [debian packages](http://packages.debian.org/libsimgrid-dev).
-
-Please note that your distribution may ship with an old version of
-SimGrid; you may want to use [a newer release](https://gforge.inria.fr/frs/?group_id=12)
-or even [clone our git repository](https://gforge.inria.fr/frs/?group_id=12)
-(a [GitHub mirror](https://github.com/mquinson/simgrid) is also available).
