We we review code

## What are the key topics that will be covered in the workshop?

* Why we do code review at CYF (e.g. to teach/learn, to prepare for a professional skill, to practice git)
* What are objectives are of code review at CYF (producing perfect PRs, solidifying understanding)

## What knowledge does the trainee need before starting?

* Familiarity with the GitHub PR interface.
* Has received at least one code review.

## What are the topics that will **not** be covered in the workshop?

Any details of code itself - we're just talking about process not content.
