 <Steps>
   <Step title="Create a Schedule">
     Go to **Schedule Management**, click "Create Schedule"
+    - **Schedule Name**: 1–40 characters, must be unique within the account
+    - **Owning Team**: Specifies which team manages this schedule; team members gain edit permissions for this schedule
     - **Schedule Description**: Supports Markdown syntax, content can be included in notifications
-    - **Owning Team**: Specifies which team manages this schedule, not the on-call personnel
   </Step>
-  <Step title="Set Notification Reminders">
-    To prevent forgetting shifts or handoffs, the system provides two reminder types:
-    - **Handoff Notification**: N minutes before rotation (e.g., 15 minutes ahead), notifies both the outgoing and incoming personnel
-    - **On-duty Notification**: During on-call periods, sends a daily notification at a fixed time (e.g., 9:00 AM) reminding who's currently on-call
-    - **Channels**: Supports email, SMS, phone, IM (Feishu/Lark, Dingtalk, WeCom)
+  <Step title="Set Shift Notifications">
+    To prevent forgetting shifts or handoffs, the system provides two notification triggers:
+    - **Advance Notification**: Notifies both outgoing and incoming personnel N minutes before handoff (in 5-minute increments)
+    - **Scheduled Notification**: Sends a daily notification at a fixed time (e.g., 8:00 AM) reminding who is currently on-call
+
+    After enabling either notification trigger, you need to configure notification channels:
+
+    - **Personal Channels**: Send notifications directly to on-call personnel
+      - **Follow personal preference**: Each responder receives notifications via their personally configured channels
+      - **Follow unified settings**: Administrators select notification channels (SMS, email, and integrated IM apps)
+    - **Group Chat Channels**: Send notifications to group chats, supporting the following platforms:
+      - Feishu app, DingTalk app, Slack app (select chat groups via integrated IM apps)
+      - WeCom bot, DingTalk bot, Feishu bot (send via webhook URL)
+      - Slack bot, Telegram bot, Zoom bot
   </Step>
   <Step title="Define On-call Rules">
     This is the core step. You can add one or more layers of rules. Each layer includes:
-    - **On-call Personnel**: Select members participating in rotation
-    - **Rotation Cycle**: Supports day, week, custom duration
-    - **Time Restriction**: (Optional) This rule only takes effect during specific time periods
+
+    - **On-call Personnel**: Select members participating in rotation, supports grouping and primary/backup roles
+    - **Rotation Cycle**: Supports four units — hour, day, week, and month — with values from 1 to 30. For example, "2 days" means rotation every 2 days
+    - **Handoff Time**: When the rotation cycle is 1 week, you can specify the day and time for handoff
+    - **Fair Rotation**: When enabled, the system automatically adjusts rotation order to prevent someone from always being on-call during weekends
+    - **Date Mask**: Select which days of the week to schedule on-call. See [Date mask and continuous rotation](#date-mask-and-continuous-rotation) for details
+    - **Time Restriction**: (Optional) Restrict actual on-call hours within each rotation cycle, with the following modes:
+      - **No restriction**: Members are on-call for the entire rotation cycle
+      - **Daily**: Set daily on-call time ranges (e.g., 09:00–18:00), multiple periods can be added
+      - **Weekly**: Set day+time on-call ranges (e.g., Monday 09:00 – Friday 18:00), multiple periods can be added
+
+    <Note>When date mask is enabled, the "Weekly" restriction mode is unavailable since the date mask already provides day-of-week control. After setting time restrictions, there may be gaps with no one on-call — ensure other rules provide coverage.</Note>
