Add link checker to detect broken links (#18) 
Just a suggestion, the link checker would detect broken links via github action. 

Might be helpful for a repo which consists a lot of markdown files.

guide: warn about block profiler overhead (#15) 
After internal investigations, we found that poor block profiler
configuration can lead to noticeable, and in some cases quite
significant, overhead in production. Add a warning. I also updated the
recommended rates to a 100,000,000, which is a more conservative rate
and would hopefully guard against unexpected performance issues if the
suggested configuration was applied to a production app.

guide: add note about changing mutex rate during execution (#11) 
When a mutex profile is reported, the counts and delays in the profile
are scaled based on the most recently set rate. So if an application has
changed its profile rate at runtime and collected different samples at
different sampling rates, the samples won't be adjusted correctly when
the pprof is written.
