-## Welcome
+## Step 1: Create your first codespace and push code
 
-GitHub Codespaces is a development environment that's hosted in the cloud.
+_Welcome to "Develop code using GitHub Codespaces and Visual Studio Code"! :wave:_
 
-- **Who this is for**: Developers, DevOps Engineers, Engineering Managers, Product Managers.
-- **What you'll learn**: How to create a codespace, push code from a codespace, select a custom image, and customize a codespace.
-- **What you'll build**: A codespace with devcontainer.json files, customizations, and personalizations.
-- **Prerequisites**: If you need to learn about Visual Studio Code, read [Visual Studio Code Docs](https://code.visualstudio.com/docs) first.
-- **How long**: This course can be completed in less than an hour.
+**What's the big deal about using a codespace for software development?** A codespace is a development environment that's hosted in the cloud. You can customize your project for GitHub Codespaces by committing configuration files to your repository (also known as configuration-as-code), which creates a repeatable codespace configuration for all users of your project. Each codespace you create is hosted by GitHub in a Docker container that runs on a virtual machine. You can choose the type of machine you want to use depending on the resources you need.
 
-In this course, you will:
+GitHub offers a range of features to help your development team customize a codespace to reach peak configuration and performance needs. For example, you can:
 
-1. Create your first codespace
-2. Add a custom image
-3. Customize your codespace
-4. Personalize your codespace
+- Create a codespace from your repository.
+- Push code from the codespace to your repository.
+- Use VS Code to develop code.
+- Customize the codespace with custom images.
+- Manage the codespace.
 
-### How to start this course
+To begin developing using GitHub Codespaces, you can create a codespace from a template or from any branch or commit in a repository. When you create a codespace from a template, you can start from a blank template or choose a template suitable for the work you're doing.
 
-<!-- For start course, run in JavaScript:
-'https://github.com/new?' + new URLSearchParams({
-  template_owner: 'skills',
-  template_name: 'code-with-codespaces',
-  owner: '@me',
-  name: 'skills-code-with-codespaces',
-  description: 'My clone repository',
-  visibility: 'public',
-}).toString()

+### :keyboard: Activity: Start a codespace
+
+**We recommend opening another browser tab to work through the following activities so you can keep these instructions open for reference.**
+
+1. Start from the landing page of your repository.
+1. Click the green **Code** button located in the middle of the page.
+1. Select the **Codespaces** tab in the box that pops up and then click the **Create codespace on main** button.
+
+   > Wait about 2 minutes for the codespace to spin itself up.
+   > **Note**: It's a virtual machine spinning up in the background.
+
+1. Verify your codespace is running. The browser should contain a VS Code web-based editor and a terminal should be present such as the below:
+   ![codespace1](https://user-images.githubusercontent.com/26442605/207355196-71aab43f-35a9-495b-bcfe-bf3773c2f1b3.png)
+
+### :keyboard: Activity: Push code to your repository from the codespace
+
+1. From inside the codespace in the VS Code explorer window, select the `index.html` file.
+1. Replace the **h1** header with the below:
+
+   ```html
+   <h1>Hello from the codespace!</h1>
+   ```
+
+1. Save the file.
+   > **Note**: The file should autosave.
+1. Use the VS Code terminal to commit the file change by entering the following commit message:
+
+   ```shell
+   git commit -a -m "Adding hello from the codespace!"
+   ```
+
+1. Push the changes back to your repository. From the VS Code terminal, enter:
 
-[![start-course](https://user-images.githubusercontent.com/1221423/235727646-4a590299-ffe5-480d-8cd5-8194ea184546.svg)](https://github.com/new?template_owner=skills&template_name=code-with-codespaces&owner=%40me&name=skills-code-with-codespaces&description=My+clone+repository&visibility=public)
+   ```shell
+   git push
+   ```
 
-1. Right-click **Start course** and open the link in a new tab.
-2. In the new tab, most of the prompts will automatically fill in for you.
-   - For owner, choose your personal account or an organization to host the repository.
-   - We recommend creating a public repository, as private repositories will [use Actions minutes](https://docs.github.com/en/billing/managing-billing-for-github-actions/about-billing-for-github-actions).
-   - Scroll down and click the **Create repository** button at the bottom of the form.
-3. After your new repository is created, wait about 20 seconds, then refresh the page. Follow the step-by-step instructions in the new repository's README.
+1. Your code has been pushed to your repository!
+1. Switch back to the homepage of your repository and view the `index.html` to verify the new code was pushed to your repository.
+1. Wait about 20 seconds then refresh this page (the one you're following instructions from). [GitHub Actions](https://docs.github.com/en/actions) will automatically update to the next step.
