Learning Git

Learning Git is something that has been on my to-do-list for quite a while now, and I have finally gotten around to it. I have been following this tutorial, which includes some basic commands and also some more advanced stuff towards the end. I also created an account on GitHub where I will start adding my solutions to the Rosalind problems.

To try it out, I made a repository and pushed my solution to "Introduction to Alternative Splicing" into it. And immediately ran into a problem. I got the following error message:

! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/ssjunnebo/Rosalind.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details

A quick bit of Google-ing told me that the problem was that when I created the repository on GitHub, I added a README, and since this wasn't available locally on my computer I first needed to merge the GitHub repository with the folder on my computer. I did this using the following command:

> git pull origin master

 I was then able to push my first piece of code onto GitHub!
