[DISCUSSION][Website] Optimization

[victor chan]

I am doing website optimization, I have some ideas, I look forward to your
suggestions.
1. I think we need to bring together the documents for our projects.
2. We need to merge the "user manual" and the "getting started". Now, they
are displayed separately on the website, which will make the user read
discontinuous.
3. We need to use the same documentation framework in each project so that
they can be easily integrated into the website.
