+# Script to delete your history message from groups
+
+This script will automatically delete your history message in all joined groups.  
+It will check the latest `n` messages of each joined group, and delete the message if:
+
+   1. It was sent from you
+   2. The group is not whitelisted
+   3. The group was sent at least `t` seconds ago
+
+It's recommended to auto-run this script daily to protect your privacy.
+
+这个脚本会自动从所有已加入群组删除你的历史消息.  
+它会检查每个已加入群组的最近的n条消息, 并且在满足以下条件时删除它:
+
+1. 消息是你发的
+2. 这个群组不在白名单里
+3. 这个消息是一定时间段前发的
+
+我们建议你每天自动运行一次此脚本, 来保护你的隐私.
