+<summary><strong>What about the Chunky SpigotMC plugin?</strong></summary>
+
+> The [Chunky SpigotMC plugin](https://www.spigotmc.org/resources/chunky.81534/) is an unfortunate name collision and is unrelated to this project. Chunky (SpigotMC plugin) is a handy plugin to quickly pre-generate server chunks should you need that functionality. You can also find [Chunky (SpigotMC Plugin) on GitHub](https://github.com/pop4959/Chunky).
