@TechGeekRahul Did you even run the project locally? I think you didn't. I can see the basic mistakes in your file; it is because there is an error. Please take time to go through the code base and do your research regarding the usage of mdx etc. Please use Astro starlight components such as tab, code etc to present the contents visually not in the md format.

Please note that everything will be reviewed.
