3. After opening the file, click on the "Tools" tab.
4. In the Tools menu, scroll down until you see the "Fill & Sign" option. Depending on your settings, this option may also be available on the right side of your screen.
5. The Fill & Sign menu will now be open at the top. Click on the "Sign" icon.
6. After clicking the "Sign" icon select the "Add Signature" option to add your signature.
7. After clicking "Add Signature" a box will pop up for you to type in your name.
8. After entering your name you may change the appearance of your signature using the "Change Style" option on the right. After you have completed typing your name and setting your signature's style click the "Apply" at the bottom of the box. You only need to enter and style your name one time, as once your signature is saved it will be added to the drop-down menu after clicking on the "Sign" icon in place of the "Add Signature" option.
9. You can now drag and drop your signature to where you would like to place it. Clicking on the small or large "A" will change the size of the signature.

10. After you have completed positioning and resizing your signature you can click on the X on the Fill & Sign toolbar to close the signature tool.
Your signature has now been added to the document. You may save or continue to work on it.
