guideline

please divide the problem into small parts
if you found youself cannot understand the problem, please stop and ask how to do
if you found youself cannot solve the problem, plesae stop and ask how to do
review the whole solution before you reply to user
if code syntax is already there, do follow (e.g. naming convention, syntax) the existing code
example for page can be found in ./src/app/_helloworld/page.tsx
example for component can be found in ./src/components/_helloworld/index.tsx
no need to explain the reason until you are told to do so
no need to show me the code change, at the end just simple summary in point form is ok

Thanks
