# (PART) Communicate {-}
# Introduction
Parts 1 through 4 have shown you how to understand what is happening in your data, but it won't matter how well you understand your data if you cannot communicate what you find with others. To be effective, you will need to share your work in a way that your audience can comprehend. Your audience might be
* fellow scientists who will want to reproduce the work
* non-scientists who will want to understand your findings in plain terms
* or yourself (in the future) who will be thankful if you make your work easy to re-learn and recreate
__Part 5__ discusses communication, and how you can use R Markdown to save and share your work in an incredibly efficient way.
```{r echo = FALSE, out.width = "75%"}
knitr::include_graphics("diagrams/data-science-communicate.png")
```
This part will conspicuously not cover one technology that I feel is essential to a particular type of communication: collaboration. Whenever you collaborate with one or more people, you can make your life much easier by using version control software, specifically Git and Github. We recommend two free resources that will teach you about Git.
First, Hadley has written a chapter that explains how to use Git and Github, which is available online,

Second, Jenny Bryan has written a terrific book on how R users can use git, which is also available for free online,
