+### On the Use Cases of SERP
+Based on my personal research into the use of the WelsonJS project as a SERP tool, I found that its usage is overwhelmingly high among e-commerce companies (including live commerce). However, this project was not specifically designed for the e-commerce sector.
+
+Nonetheless, if you have any questions during your use, feel free to ask, and I will do my best to help you find the optimal solution. Thank you.
