Torah Readers:
The text copy you received in the mail is from a Tikkun (a text used by Torah readers to prepare their reading from the scroll itself). You are expected to read from the actual Torah scroll. Please note that the Torah trope for the mornings of Rosh Hashanah and the morning of Yom Kippur is a special trope for the High Holy Days, as you can hear on the recordings.
Haftarah Readers:
The text copy you received in the mail is from the Machzor (High Holy Day prayer book). During the service you can read your Haftarah section from the sheet mailed to you.
