+
+# Intro
+
+Inspiration comes from video [《你 问 我 打 ！》](https://www.bilibili.com/video/BV13V4y1W7X6/)
+
+It is an upgraded version of the plugin in the video, and the selection issue is not just yes or no, multiple options can be customized
+
+I also added a question and answer for filling in the blank, allowing players from all servers to jointly determine whether it is correct or not
+
+# Usage
+
+Download the latest version in [Release](https://github.com/MinecraftProgrammingTeam/AnswerIt/releases/latest) and put the jar file in a Minecraft server with BukkitAPI in plugins folder, and restart the server to apply it.
+
+Test Environment("Server + Client"): `Paper1.16.5 + Minecraft 1.16.5`
+
+Suggested server version>=1.16.5
