The steps described in the `Getting Started` section are not detailed and accurate enough.

I get started the workshop with the steps described in the Getting Started section, but I met the following error, I don't know how to fix these errors:

You're supposed to open the corresponding exercise file (

rust-telemetry-workshop/exercises/01_structured_logging/00_intro/src/main.rs

Line 1 in cb8579d

//! # Logs

) and follow the instructions there.
Tests should never be edited: you always work on the non-test code.

99% of the time you need to add new code where you find a todo!() invocation or a // TODO comment.

There is also a solutions branch you can refer to.
