+# FastMud
+
+Maybe you've already thought the following:
+
+> "If glass bottles can turn dirt into mud, then why doesn't a bucket of water work? Wouldn't it make more sense if running water could make mud? 🤔"
+
+And it was thinking a lot about this, spending a lot of time, that I decided to create this plugin for a personal logic correction, and I decided to share it with you 😁
+
+## 🎉 Features
+
+- When player uses water bucket.
+- When water flows.
