Customising your Chrome homepage is simple. First, open Chrome and click on the three vertical dots in the top-right corner to access the menu. Select "Settings." In the "Appearance" section, find the "Show home button" option and enable it. Below that, you can choose to use the "New Tab page" or enter a specific website URL as your homepage. To set a custom webpage, click "Enter custom web address" and type in the URL. Your chosen homepage will now open every time you launch Chrome.
