To add a signature in Google Docs, you can follow these steps:
1. Open your Google Docs document.
2. Click on "Insert" in the menu at the top.
3. Hover over "Drawing" in the dropdown menu.
4. In the sub-menu that appears, select "+ New."
5. A drawing canvas will appear. Click on the "Line" tool (it looks like a diagonal line) in the toolbar at the top.
6. Choose "Scribble" from the drop-down menu.
7. Use your mouse or touchpad to draw your signature on the canvas.
8. Once you're satisfied with your signature, click "Save and Close" in the top-right corner of the drawing canvas.
9. Your signature will now be inserted into your Google Docs document. You can click and drag it to position it wherever you like within the document.
Remember that this method inserts an image of your signature, so if you need a legally binding signature, you may need to explore other options such as using a digital signature tool or physically signing a printed copy of the document.
