+##### Using GUI Tools for Git
+If you are not comfortable with the command line, you can use GUI tools to handle Git operations. Here are some example tools:

+- [GitKraken](https://www.gitkraken.com/): A powerful Git GUI client for Windows, MacOS, and Linux - Free for use with Public Repos, like this one!
+- [GitHub Desktop](https://desktop.github.com/): A simple and easy-to-use Git client for Windows and MacOS. 
+These tools provide a visual interface for Git operations, making it easier to manage branches, commits, and pull requests.

+2. **Work on the Branch**: Make your changes and commit them to your branch.
+```bash
+git add .
+git commit -m "Your commit message"
+```
+3. **Create a Pull Request (PR)**: Once you have completed your work, push your branch to the repository and create a pull request.
+```bash
+git push origin your-branch-name
+```
