-## Exercise: Branch Out with GitHub Branches! 🌲
+## Exercise 1: Setting Up and Collaborating on GitHub 🌐
 
-**Objective**: Delve into one of Git's most powerful features: branching. By the end of this exercise, you'll have created, navigated, and understood the essence of branches in GitHub, setting a solid foundation for parallel development and experimentation without disrupting the main codebase.
+**Objective**: Get a hands-on introduction to various GitHub features such as profile customization, forking, and pull requests. By the end of this exercise, you'll have a personalized GitHub profile, a forked repository, and experience collaborating on a project.
 
 ### Instructions:
 
-1. **Understanding Branches**: Before making one, it's crucial to grasp the concept. A branch in Git is essentially a unique set of code changes with a unique name. It represents an independent line of development, allowing you to work on multiple features or fixes simultaneously without them affecting each other.
+1. **Craft Your GitHub Identity**: 
+   - Visit the [GitHub guide](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/managing-your-profile-readme).
+   - Create a `README.md` to personalize your profile.
+
+2. **Make Your Copy**: 
+   - Navigate to the [forking instructions](https://docs.github.com/en/get-started/quickstart/fork-a-repo#forking-a-repository).
+   - Fork our [project repository](https://github.com/grundkurs-git/.github), creating your personal copy
+      - Use "grundkurs-git" as name
+
+3. **Roster Update**:
+   - Within your forked repository, find the **Participants HS23** list.
+   - Edit the file to include a link to your GitHub profile.
+
+<details>
+
+<summary>Tips</summary>
+
+The list is located under `profile/README.md`
+
+</details>
+
+
+4. **Become a Contributor**:
+   - Once your profile link is added in your local copy, initiate a Pull Request to propose your updates to the [course project](https://github.com/grundkurs-git/.github).
+      - To initiate a pull request, locate the "Contribute" dropdown (often found towards the upper right).
+      - Click on "Contribute" and select "Open pull request".
+      - Ensure you're proposing changes from your branch/fork to the main branch of the [course project](https://github.com/grundkurs-git/.github).
+      - Submit your pull request with a succinct, descriptive message detailing your proposed alterations.
+
+### Reflection:
+
+1. Describe the significance of forking in collaborative projects.
+2. What is the purpose of a Pull Request and how does it facilitate collaboration?
+
+Give yourself a pat on the back! 🌟 These foundational steps are your gateway to a world of collaborative coding and open-source contributions. Keep up the momentum!
 
-2. **Switch Between Branches**:
-   - Find the drop-down menu labeled "main".
-   - Click on it and select "exercise 1"
-   - Notice how the codebase changes as you switch between them.
