There is one default command that BossBarAPI comes with and that is /bossbar which creates a bossbar with the text "Countdown" and the bar slowly goes down
Here is a guide to the API:
To create a BossBar do
```BossBar bar = new BossBar(player)```
This will create a bossbar instance but wont spawn in the bossbar itself to the player
To set the Bars health do
```bar.setBarHealth(int)```
To set the bar's text do:
```bar.setText(String)```
If these values are not set before the bossbar is displayed, they will default to 200 which is the bar's full health and "A Bossbar!"
there are also getters for these 2 methods
To display a bossbar, use
```bar.display()```
To delete the bossbar, do
```bar.delete```
There is also a `bar.getLocation` which returns the location of the Enderdragon but you will most likely never use this method
