Download the file to your computer and open it in Adobe Reader.
Highlight the words. Open the Text Properties Box by pressing CTRL and E (or CMD and E on a MAC). (My files will not work on phones or tablets; only on computers.)
With the words highlighted, type new words right over top.
Or, you can click at the end of the line of text, delete out the text for that line by using the Backspace key on your keyboard, and then type new text.
If you mess up, just go to Edit > Undo Typing. Then try again.
If the text properties box says "No Current Selection" just use your mouse to click on the editable text.
