Github setup

Github setup includes - creating or finding an existing remote github repository url - syncing that with your files (on your computer, on rhea, on PSC, etc) - authenticating with github for git push permissions

• http://github.com/new or Home > green new repo
• Follow form to assign a name. only add readme, lic, etc if no project files exist yet
• Follow the instructions github provides

  add_remote.bash

  cd my-exsiting-data/ # go to the directory of your existing code
  git remote add origin git@github.com:$USER/$REPONAME
  git push -u origin main

• Copy the ssh url of your new repository. Green <> Code button > Local Tab > SSH header.

• Clone the copied url like git clone git@github.com/$USER/$REPO

For git push to github, you'll need some way to confirm your credentials. Authentication can happen with ssh keys (recommended) or an app password

git push can use ssh authentication. You need a key likely in ~/.ssh/id_ed25519.pub.

Contents of ~/.ssh/id_ed25519.pub should be pasted into new ssh key modal on https://github.com/settings/keys ¹⁾

If ~/.ssh/id_ed25519.pub doesn't exist, ssh-keygen can make it (use empty password for convenience. hit enter at password prompt to leave blank). See more documentaiton on github

To push to https (vs ssh like git@) repos, you'll need to use a personal authentication token when prompted for a password. See github's documentation
