@ -211,7 +211,7 @@ Congrats, you have installed MPI!
Many Julia package names end with `.jl`. This is just a way of signaling that a package is written in Julia. When using such packages, the `.jl` needs to be omitted. In this case, we have isntalled the `MPI.jl` package even though we have only typed `MPI` in the REPL. Many Julia package names end with `.jl`.

!!! note !!! note
The package you have installed it is the Julia interface to MPI, called `MPI.jl`. Note that it is not a MPI library by itself. It is just a thin wrapper between MPI and Julia. To use this interface, you need an actual MPI library installed in your system such as OpenMPI or MPICH. Julia downloads and installs a MPI library for you, but it is also possible to use a MPI library already available in your system. This is useful, e.g., when running on HPC clusters. See the documentation of `MPI.jl` for further details. The package you have installed it is the Julia interface to MPI, called `MPI.jl`. Note that it is not a MPI library by itself.

To check that the package was installed properly, exit package mode by pressing the backspace key several times, and run it again To check that the package was installed properly, exit package mode by pressing the backspace key several times, and run it again
