-# Introduction to GitHub
+# Using Git and GitHub for research and software development

-### Why another GitHub tutorial?
-Hi there.
+### Why use Git and GitHub?
+So you've been working on some cool visualization pipeline or new machine learning algorithm that can help a bunch of people in lab, is necessary for a programming project, or is the software package you're publishing. You can send the source code files by email or Google Drive. But what if you make changes that make the software even more useful. And even worse - other people have also contributed to your code, creating several versions of the same file. How can you compile all of these different file versions to one (hopefully) working script? 
 
-There are so many introductory tutorials for using [Git](https://git-scm.com/docs) and [GitHub](https://guides.github.com/activities/hello-world/), which can be daunting to compile and apply to research projects. My goal is to create a concise, step-by-step resource for maintaining your software projects on GitHub.
+Git. And GitHub.
+
+These [version control](https://www.atlassian.com/git/tutorials/what-is-version-control) tools allow teams of people to manage changes in source code over time. Anyone can download the latest version of your project. Also, anyone can upload their improvements on your project, making it super easy to share code. Finally, it save your code as you add onto this database, so if you or your teammates introduce bugs into the source code, you can re-wind the clock and download the latest working version. 
 
-Everything you need is to get started can be found [here]().
+These are just a few of the many positive aspects of version control. For a more in-depth discussion, you can read the official documentation (which I **highly** encourage you to do), but this repository is meant to be a functional guide to quickly using Git and GitHub for your research project.
