Few nits:

1. At the very beginning where we say

You can enable APM by installing the Agent with either:

Datadog Operator Datadog Helm chart

The links don't lead anywhere.

2. The section

Here you can also optionally configure the following: Enabling or disabling instrumentation for namespaces. Specifying tracing library versions. Choosing specific pod specifications.

I'm not sure Choosing specific pod specifications needs to be part of this instruction. It's an alternate way to SSI of instrumentation, not the part of it.
