The following page describes the setup for a bukkit/spigot plugin.
To use Tubing for a bungee or velocity plugin the dependencies are slightly different.
This is explained in its own section.
Maven
Add following dependency to your pom.xml. All Tubing dependencies are fat jars. So we can and should exclude any transitive dependency.
Create your main plugin class and extend the TubingBukkitPlugin class.
Override the enable and disable method. Configuration is automatically instantiated if there is a config.yml file present.
Look into the command and event listeners documentation to start creation your plugin.
Checkout the beans section to see how we can register Tubing beans and inject them into other Tubing Beans
