======  Using GitHub for Collaborative Coding on the Cluster ====== 

How-to-Guide for connecting your GitHub account to the cluster, creating a new repository, cloning it to the cluster and collaborating on the cluster.

==== 1. Step: Connect Github Account ====

**Connect your Github account to the cluster (more detailed info see: https://docs.gitlab.com/ee/user/ssh.html#add-an-ssh-key-to-your-gitlab-account)**

//(please skip if you have used GitHub on the cluster before)//

Create an SSH key on the cluster:

<code>
ssh-keygen -t ed25519 -C "<youremail@university.com>”
</code>

Navigate to the folder where it was placed (usually in “/home/user/.ssh/id_ed25519_sk.pub”) and copy the public key (e.g. “ssh-rsa AAAAB3NzaC1...= matiasrus@dunwich.sleep.ru.is”)

Place the public key on your GitHub account in the browser under //your user > settings > SSH and GPC keys//

==== 2. Step: Create Repository ====

Set up a new GitHub repository on through the Github website (https://github.com)


==== 3. Step: Clone the new GitHub project to the cluster ====

You can find this shareable link on the start page of the repository using GitHub in the browser. If you are using a private repository, you additionally need to give your fellow users access rights. For this navigate to //settings > collaborators > add people// and add them through their GitHub user names.

<code>
git clone git@github.com:hiluka/cluster_git.git
</code>

==== 4. Step: Collaborate! ====

Before you work on the project: 
<code> git pull </code>

After you created new code files / plots / results: 
<code> git add [changed file or * for all files] </code> 

Then save your current state: 

<code> git commit -m “info about my updates” </code>

Then push your state to the shared repository:

<code> git push </code>
