 SSJ runs on Python 3.7 or newer, and requires Python's core numerical libraries (NumPy, SciPy, Numba). We recommend that you first install the latest [Anaconda](https://www.anaconda.com/distribution/) distribution. This includes all of the packages and tools that you will need to run our code. 
 
-To install SSJ, open a terminal and type *(COMING SOON)*
+To install SSJ, open a terminal and type

-*Optional package*: SSJ also provides an interface for plotting the directed acyclic graph (DAG) representation of models. This feature requires both the [Graphviz](https://www.graphviz.org/) graph drawing software and the corresponding [Python package](https://pypi.org/project/graphviz/). If you have the Anaconda Python distribution, you can try installing both by typing `conda install -c conda-forge python-graphviz` at a terminal.
