137 +We shall now move on to install the NEST simulator. Unlike Brian2, NEST is not a Python package and therefore its installation is a bit more involved. We shall install the NEST module along with PyNEST, which is a Python interface for controlling the NEST kernel.

139 +We first install the NEST module. Version 2.20 is currently supported by PyNN, and it is likely that other versions of NEST might have issues when used with the current version of PyNN. The installation is done by first adding the PPA repository for NEST and updating apt, followed by the installation of NEST itself.
