 ### Detailed Configuration Using Workload Configuration File
 
+* Vertical Scaling: Based on historical GPU resource usage data, the community VPA Histogram algorithm is employed.
+The estimates generated by the VPA algorithm consist of Target, LowerBound, and UpperBound, corresponding by default to P90, P50, and P95 usage levels.
+If the current resource usage falls outside the LowerBound and UpperBound range, a recommended value is generated.
+
+>[!NOTE] Note: If enable is not set to true, or if targetResource is empty, only resource recommendations will be generated, and the recommended values will not be applied in practice.
+
+* Cron Scaling: Based on standard cron expressions, scaling takes effect when `enable` is `true` and within the `start` and `end` time range. Outside this range, resources revert to the values specified when the workload was added. [Cron Expression Reference](https://en.wikipedia.org/wiki/Cron)

 ### 使用工作负载配置文件进行详细配置
 
+* 垂直扩缩容: 基于GPU资源历史使用量数据，采用社区VPA Histogram算法实现。
+ VPA算法生成的估算值由Target、LowerBound、UpperBound组成，默认对应P90、P50、P95用量。
+ 若当前资源用量在LowerBound和UpperBound范围外，则生成推荐值。
+
+>[!NOTE] 注意：若enable不为true，或者targetResource为空，则只推荐资源值，不会实际应用资源推荐值
+
+* 定时扩缩容: 基于标准的cron表达式，当`enable`为`true`，并且在`start`和`end`范围内生效，超出时间范围则恢复至添加工作负载时指定的资源值，[Cron表达式参考](https://en.wikipedia.org/wiki/Cron)
