This is such an important part for language users and seeing how many people are for various reasons are not entirely happy with doxygen it'd be cool to list some viable alternatives.

Approximate list of links to tools I've found, just for reference:

DNS preanalyze is a way to reduce DNS analyze time:

<meta http-equiv="x-dns-prefetch-control" content="on" />
<link rel="dns-prefetch" href="http://www.baidu.com" />

The suggested command uses ping vs opening a browser, this is not correct because the browser does a HTTP request, while ping simply sends a ICMP packet.

The correct command would be using wget or curl.

Make your first pull-request 😄

The descriptions to many of the links to the products and services are quite generic. It would be quite useful if some of them could be rewritten by people that have actually used the products.

This would allow visitors to get a clearer picture of what differentiates the products and services.
