Go to https://www.gmail.com/ in your computer's web browser. This will open your Gmail inbox if you're logged into your Google Account in your browser.  If you aren't logged into your Google Account, enter your email address, click Next, enter your Gmail password, and click Next to sign in. If you don't know your Gmail password, reset it and log in with your new password. If you're reporting to Google a specific error in your Gmail inbox, navigate to the error and make sure that it's displaying on-screen before proceeding. If there isn't an error you're experiencing in Gmail, skip this step. It's in the upper-right side of the Gmail page. Doing so prompts a drop-down menu. This is at the bottom of the drop-down menu. A form will open. Click the "Send feedback" white text box at the top of the form, then type in whatever you want to report to Google. Click the screenshot below the text box, then click and drag across the area you want to highlight. Click DONE to save the screenshot. If you're not reporting an actual in-Gmail error, uncheck the "Include screenshot" box. It's at the bottom of the form. Doing so will send your error report to Gmail's support team.

How would you rephrase that briefly using Vietnamese?
