# Installation
-Julia includes a very useful package manager which makes it easy to install
-packages and their requirements, as well as convenient updating features.
+
+## Prerequisites
+Granular.jl is written as a package for the [Julia programming
+language](https://julialang.org), which is a computationally efficient, yet
+high-level language. Julia also includes a very useful package manager which
+makes it easy to install packages and their requirements, as well as convenient
+updating features.
+
+### Installing Julia
+If you do not have Julia installed, download the current release from the
+[official Julia download page](https://julialang.org/downloads), or using your
+system package manager (e.g. `brew cask install julia` on macOS with the
+[Homebrew package manager](https://brew.sh)). Afterwards, the program `julia`
+can be launched from the terminal.
+
+### Installing Paraview
+The core visualization functionality of Granular.jl is based on VTK and
+ParaView. The most recent stable release can be downloaded from the [ParaView
+downloads page](https://www.paraview.org/download/). Alternatively, on macOS
+with Homebrew, Paraview can be installed from the terminal with `brew cask
+install paraview`.
## Stable installation (recommended)
The latest stable release of Granular.jl can be installed directly from the

so further investigation and diagnosis can follow.
