 ## How it works:
 
-A text buffer is used to store the text which is to be displayed. Depending on whether the display is used in portrait or landscape orientation, the text buffer has 5 lines or 10 lines.
+A text buffer is used to store the text which is to be displayed. With text size 2 (the default), depending on whether the display is used in portrait or landscape orientation, the text buffer has 5 lines or 10 lines.
 New characters are always written in the last line of the buffer, so that the text scrolls up like a classic terminal. 
 The number of possible characters per line varies between characters. In the portrait orientation, between 8 and 23 characters fit in one line. A typical text needs 9 to 11 characters. In the landscape orientation between 19 and 50 characters fit in one line. A typical text requires between 21 and 24 characters.
 When a new character is to be displayed, it draws the function on the display and checks if the position behind the character is outside the display. If so, the line is automatically wrapped and the character is displayed as the first character in the new line.
 
+With larger text sizes, fewer characters will fit per line, and fewer lines will fit on the screen.
