1) Lesson 01 - Hello World
Instantiate a Tracer
Create a simple trace
Annotate the trace
2) Lesson 02 - Context and Tracing Functions
Trace individual functions
Combine multiple spans into a single trace
Propagate the in-process context
3) Lesson 03 - Tracing RPC Requests
Trace a transaction across more than one microservice
Pass the context between processes using Inject and Extract
Apply OpenTracing-recommended tags
4) Lesson 04 - Baggage
Understand distributed context propagation
Use baggage to pass data through the call graph
5) Extra Credit
Use existing open source instrumentation
