@SergeyKleyman FYI I created a list of everywhere that agent content is included in the four main Observability documentation books. I'll start going through and adding content in, but I'll likely have questions for you on some of these.

@bmorelli25 Thank you for keeping me up to date. I assume you refer in part to what I mentioned at elastic/apm-agent-php#347, am I correct?

Oh wow, we each had the same thought 😅. Should I just move all of these links into your issue and close this one out?

Whatever is more convenient for you since you are the one that is going to do all the work :)

@bmorelli25 It seems everything is done, doesn't it?

[bmorelli25]

Indeed! Closing this out.
