Go to https://www.gmail.com/ in your computer's web browser. This will open your Gmail inbox if you're logged in. If you aren't logged into your Gmail account, enter your email address and password when prompted. It's in the upper-left side of your Gmail inbox. Doing so opens a "New Message" window in the lower-right corner of the page. If you're using the old version of Gmail, you'll click COMPOSE here instead. Click the "To" or "Recipients" text box at the top of the New Message window, then type in the email address of the person to whom you want to send your email.

If you want to apply formatting to your text (e.g., bolding, italics, or bullet points), highlight the text to which you want to apply the formatting, then click one of the formatting options at the bottom of the email window. For example, to bold a section of text, you would highlight the text and then click B at the bottom of the email. To add a file from your computer, click the "Attachments" icon at the bottom of the window, then select the file(s) you want to upload and click Open (or Choose on a Mac). You can add photos in this way, or you can upload photos directly to the email's body by clicking the "Photos" icon at the bottom of the window, clicking Upload, clicking Choose photos to upload, and selecting photos as needed. It's a blue button in the bottom-right corner of the email window. Doing so...
