+```html
+<form action="scripts/request-2-script.php" method="post">
+  <button type="submit" name="request-submit">
+    <p>Turnon Light</p>
+  </button>
+</form>
+```
+
+### Request script
+Copy the request script and change the name corespondengly so it matches with the link in [```index```](website/index.php)
+
+you also heve to change the tabel on line 21 so it matches the right log tabel
+```php
+$sql = "INSERT INTO RDL_log (given_name, family_name, email) VALUES (?, ?, ?)";
+```
+to something like
+```php
+$sql = "INSERT INTO RDL_log_2 (given_name, family_name, email) VALUES (?, ?, ?)";
+```
+
+### API
+For the api page you have to make a copy and change the taqbel to get the data from by changing line 4.
+```php
+$sql = "SELECT * FROM RDL_log";
+```
+
+### ESP32
+On the ESP32 side the only thing you have to change from the first deplayment is the URL ending.
