New to OTEL. I can't find documentation for @opentelemetry/instrumentation package

[python3js]

Hello, I'm new to OpenTelemetry and would like more information on how to instrument my library for my users.

However, I can see different integrations (in my case, TypeScript) where some libraries use the experimental instrumentation package, while others use @opentelemetry/core, @opentelemetry/sdk-node along with @opentelemetry/sdk-trace-base.

How are these two related or different from each other? Is opentelemetry-instrumentation supposed to be a replacement for sdk-trace-base, sdk-node and core?

The opentelemetry/instrumentation package is not included in the main docs on the website and it seems to only contains sdk-trace-node.

If I'm just getting started and in a "not knowing what I'm doing" phase and just experimenting with it, which one(s) should I use?
