Assuming you would like to set Google.com as your home page in the Chrome browser:
1. Open Chrome and go to google.com
2. At the top right corner of the screen, click on More
3. Select Settings from the dropdown menu that appears
4. In the On startup section, select Open a specific page or set of pages. You will then see google.com listed as your home page
5. If it is not already selected, click on the radio button next to Open this page
6. Click on the blue link that says Use current pages at the bottom of the Startup section (this will make sure any tabs that were open when you last used Chrome are still open when you start it up again)
7. Close out of settings and enjoy your new homepage!
