 There is a bit of manual effort necessary from year to year. These tasks include, but might not be limitted to:
-* update the logo for the curent year at `/server/images/header.png`
+* update the logo for the curent year at `/server/images/header.png` should be `360x170px`
 * Do a search and replace for the previous scale version (example: replace all occurances of 16x with 17x)
 * verify proper XML is being supplied by drupal from the url reflected in the `$url` variable in `room.php` and `scroll.php`
-* set `$starttime` in `scroll.php` which should reflect midnight of the first night of current year show
+* set `$starttime` in `scroll.php` which should reflect midnight of the first night of current year show. Example: if the show starts on 3/14/24, then the entry for startime should be: `$starttime = mktime(0, 0, 0, 3, 14, 2024) / 60;`.
 * set `$starttime` in `room.php` to match scroll.php
 * set `$room_lookup_table` in `room.php` to match all rooms being used for the current year
 * set `$room_lookup_table` in `index.php` to match the one in `room.php`
