### AI overview

This tutorial explains the evolution of Go's garbage collector from stop-the-world pauses to mostly concurrent collection. It introduces tri-color marking, explains the purpose of write barriers, and indicates that it will cover GOGC tuning.

### Source excerpt

How Go's GC grew from full pauses to mostly concurrent, what the tri-color algorithm does, why write barriers matter, and how to tune GC with GOGC without shooting yourself in the foot are how we will walk through in this part.
