Hands-On (Hacky Hour @ DPG spring meeting 2019, Rostock)

Installation

Online only

You can either complete this tutorial online using only GitHub, in which case you need a to have a (free) account.

• Create an account here

Alternative

Or you can use a local repository (with or without a linked GitHub account). In this case you need a local installation, instructions are as follows:

• (Recommended for Windows/MacOS) For git + a slim and essential GUI: GitHub Desktop.
• (Other OS/Else) See instructions here

Let's do this

Depending whether you use GitHub only online or a local installation, go to different websites:

• If you are using GitHub online, follow this Git Hello World! example.
• If you are using git locally, follow steps 1. to 5. of this guide.

  Note for users of GitHub Desktop:
  No dedicated examples for you today, but you can follow the link above in the GUI as well.
  The command names given are identical to the buttons you are looking for in the GUI.
  I have faith in you, you will figure it out! :)
