 The easiest setup using [Vagrant](https://www.vagrantup.com) is shown here.

 2. Run the following commands on the command line to clone the repository, create the Vagrant VM and run the Django development server.

In theory, you should be able to use any command line tool.

+### Creating a Pull Request (Workflow Suggestion)
+TODO: GitHub CLI evtl einfacher?
+
+0. (once) [Fork](https://github.com/e-valuation/EvaP/fork) the repository so you have a copy that you have write-access to.
+
+1. (once) Set up some Authentication for GitHub that allows push access. A common option is using [SSH keys](https://docs.github.com/en/authentication/connecting-to-github-with-ssh/about-ssh), the remaining instructions assume a SSH key setup.
+
+2. (once) Ensure your git remotes [git remotes](https://git-scm.com/book/en/v2/Git-Basics-Working-with-Remotes) are setup to use SSH.  To fetch the up-to-date state of the official repo, it's always useful to have an "upstream" remote configured:
+   ```bash
+   git remote set-url origin git@github.com:<your-username>/EvaP.git
+   git remote add upstream git@github.com:e-valuation/EvaP.git
+   ```
+
+3. Create a branch (`git branch -c <your-branch-name>`), commit your changes (`git add` and `git commit`), and push them (`git push`). "Push" will ask you to specify an upstream branch (`git push -u origin <branch-name>`).
+
+4. GitHub should now ask you whether you want to open a Pull Request when reloading the page. Use one of GitHub's [magic keywords](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue) (like "fixes") to create a link between your PR and the issue.
