-## Welcome
+## Step 1: Create a branch
 
-People use GitHub to build some of the most advanced technologies in the world. Whether you’re visualizing data or building a new game, there’s a whole community and set of tools on GitHub that can help you do it even better. GitHub Skills’ “Introduction to GitHub” course guides you through everything you need to start contributing in less than an hour.
+_Welcome to "Introduction to GitHub"! :wave:_
 
-- **Who is this for**: New developers, new GitHub users, and students.
-- **What you'll learn**: We'll introduce repositories, branches, commits, and pull requests.
-- **What you'll build**: We'll make a short Markdown file you can use as your [profile README](https://docs.github.com/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/managing-your-profile-readme).
-- **Prerequisites**: None. This course is a great introduction for your first day on GitHub.
-- **How long**: This course takes less than one hour to complete.
+**What is GitHub?**: GitHub is a collaboration platform that uses _[Git](https://docs.github.com/get-started/quickstart/github-glossary#git)_ for versioning. GitHub is a popular place to share and contribute to [open-source](https://docs.github.com/get-started/quickstart/github-glossary#open-source) software.

+**What is a repository?**: A _[repository](https://docs.github.com/get-started/quickstart/github-glossary#repository)_ is a project containing files and folders. A repository tracks versions of files and folders. For more information, see "[About repositories](https://docs.github.com/en/repositories/creating-and-managing-repositories/about-repositories)" from GitHub Docs.
 
-1. Create a branch
-2. Commit a file
-3. Open a pull request
-4. Merge your pull request
+**What is a branch?**: A _[branch](https://docs.github.com/en/get-started/quickstart/github-glossary#branch)_ is a parallel version of your repository. By default, your repository has one branch named `main` and it is considered to be the definitive branch. Creating additional branches allows you to copy the `main` branch of your repository and safely make any changes without disrupting the main project. Many people use branches to work on specific features without affecting any other parts of the project.
 
-### How to start this course
+Branches allow you to separate your work from the `main` branch. In other words, everyone's work is safe while you contribute. For more information, see "[About branches](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-branches)".

+**What is a profile README?**: A _[profile README](https://docs.github.com/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/managing-your-profile-readme)_ is essentially an "About me" section on your GitHub profile where you can share information about yourself with the community on GitHub.com. GitHub shows your profile README at the top of your profile page. For more information, see "[Managing your profile README](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/managing-your-profile-readme)".
