# Welcome to a SESYNC Training Event
This document explains how to create and contribute to your own GitHub repository comprised of the event's worksheets. The steps below use the git version control system and the RStudio IDE.
1. **Configure git**
1. **Create a new project in RStudio**
1. **Create a RSA Key Pair (Recommended)**
1. **Sync to a corresponding repository on GitHub**
## 1. Configure git
The first time you work with git on your computer, you should tell it your name and email address. This populates the author metadata associated with your commits. GitHub will associate commits with user accounts by matching e-mail addresses, so use the same one! From a terminal (e.g. RStudio's "Tools > Terminal"), execute the following two lines with appropriate substitutions for your name and email:
git config --global "J. Doe"
git config --global
## 2. Create a new project in RStudio
Download the ZIP archive of the [handouts], unzip them to an appropriate location, and rename the folder containing the worksheets to whatever name you like for your project/repository. In RStudio, choose "File > New Project > Existing Directory", browse to the newly-named folder, and clicke "Create Project".
## 3. Add version control
In RStudio, choose "Tools > Version Control > Project Setup ..." and select "git" for your version control system. Yes, you do want to initialize a new repo. Yes, restart RStudio too. The new "Git" tab provides utilities for interacting with git (i.e. a simple git GUI).
Highlight all the files, check any box, wait for it, and then click "Commit". In the window that opens, enter a commit message (e.g. "initial commit") and click "Commit".
## 4. Create a RSA Key Pair (Recommended)
Setting up an RSA key pair between your GitHub account and your computer allows you to sync to your repository on GitHub without typing in a password. To set up a key pair, follow these detailed [instructions]( written out by Adam Wilson, a professor of Geography from the University at Buffalo.
## 5. Sync to a corresponding repository on GitHub
Login to your account on Click on the "+" sign and choose to create a new repository. Name the "repo" like your RStudio project, add a description (optional), and "Create repository". Now that the "origin" repository exists under your account on GitHub, you can pair it with your local "clone". Choose SSH or HTTPS and follow the instructions under "…or push an existing repository from the command line" using the RStudio terminal.
Commits in your RStudio project can now be pushed to (or pulled from) your GitHub repository.
A `` file is a very useful component of any project
repository; it is the first file that unfamiliar users will open to
learn about your project. If this course uses GitHub, you will also
notice that the is automatically rendered on GitHub as a
simple "homepage" for your project. Instructions for creating your own
GitHub repository from these files may be given during the course. The
same instructions are also summarized in [].
## Data
If this project does not contain a data folder, the way to access data
for the worksheets depends on whether you are using RStudio Server and
Jupyter hosted by SESYNC or your own compute resources.
To access the data from a SESYNC hosted environment, open RStudio and
enter the following command at the `>` prompt.
file.symlink('/nfs/public-data/training', 'data')
Otherwise, download the "" folder from the course syllabus (if
not currently there, it will be posted after the course), and unzip it
to this "handouts" folder. The result should be a subdirectory called
"data" within this project.
