Here I am again lost and confused upgrading from Classic to Threads. I was successful in turning on a custom island but I am confused to what I see in the control panel and what my options are to insert some code.

I open the Custom Islands 1 menu in the control panel for the first time and I see some code already there in the body section.
Quote
/* PHP CODE HERE, IF NECESSARY */

/* DO NOT CHANGE THE LINE BELOW */
$body = <<<EOF

{$user['LOGIN_NAME']}
{$user['DISPLAY_NAME']}
{$user['USER_ID']}


EOF;
/* DO NOT CHANGE THE LINE ABOVE */
So I insert some html just above the EOF; line and success.
I do not know what some of this existing stuff means other than I see the comment tags and some variable names($xxx) but it works and I move on.
I open Custom Islands 2 menu and I see in the body section
Quote
$time = time();

/* BODY HERE */
$body = <<<EOF

EOF;
Different from the first Island.
I open Island 3 thru 10 and I see
Quote
/* PHP CODE HERE */

/* BODY HERE */
$body = <<<EOF
EOF;
Different again.
I am going to make an assumption that the first and second island must have some extra code to present some type of example of how the island worked in prior versions and the 3rd Island code is what the minimum requirement is to create an island.If I wish to insert some HTML insert it between the <<<EOF and the EOF; tag. Not sure what you could place above the $body field?
1. If not could someone explain the difference and how to use this?
2. Could someone provide some basic code to provide some examples on how to use this feature.
