+
+-----
+Usage
+-----
+
+This cog is designed for "filtering" unwanted words and phrases from a server.
+
+It provides tools to manage a list of words or sentences, and to customize automatic actions to be taken against users who use those words in channels or in their name/nickname.
+
+This can be used to prevent inappropriate language, off-topic discussions, invite links, and more.
