+### `display_title(players, type, title?, fadeInTicks?, stayTicks?, fadeOutTicks),`
+
+Sends the player (or players if `players` is a list) a title of a specific type, with optionally some times.
+ * `players` is either an online player or a list of players. When sending a single player, it will throw if the player is invalid or offline.
+ * `type` is either `'title'`, `'subtitle'`, `actionbar` or `clear`.
+   Note: `subtitle` will only be displayed if there is a title being displayed (can be an empty one)
+ * `title` is what title to send to the player. It is required except for `clear` type. Can be a text formatted using `format()`
+ * `...Ticks` are the number of ticks the title will stay in that state.
+   If not specified, it will use current defaults (those defaults may have changed from a previous `/title times` execution).
+   Executing with those will set the times to the specified ones.
+   Note that `actionbar` type doesn't support changing times (vanilla bug, see [MC-106167](https://bugs.mojang.com/browse/MC-106167)).

 ### `logger(msg), logger(type, msg)`
 
 Prints the message to system logs, and not to chat. By default prints an info, unless you specify otherwise in the `type` parameter.
