 Packaging your software is one of the important steps in a software project to make it both findable and accessible. This session will provide you with an understanding of why and when packaging is useful, what different standards exist to package Python and R projects and take you through each step of the packaging process through follow-along demonstrations for both Python and R (delivered by Emma Rand). 
 
-**Prerequisites:** There are a number of prerequisites if you'd like to follow-along. R users should ensure they have a GitHub account, git, R, and RStudio installed, and Windows users in particular will need to install the package development toolchain as detailed in [Emma's talk repository](https://github.com/3mmaRand/make-an-r-pkg/blob/main/prerequisite-guides/install-pkg-dev-tools.md).
