Great talk by Yuri Shkuro from Uber, which is highly involved in the world of tracing,
Has worked a lot on OpenTracing (the standard for tracing apis), and Jaeger in particular (the tool we're using).

Nice tutorial that walks you through creating your first spans, seeing how they can span through multiple services.
Good way to learn the barebones API 👍🏻
