 - up until this point, the course has been primarily focussed on technical practices, tools, and infrastructure, and primarily from the perspective of a single developer/researcher, albeit within a team environment
 - in this section, we are going to start broadening our attention to the collaborative side of software development
   - there are primarily two practices that facilitate collaboration: code review and package release
-- code review has many benefits, but top among them is that it provides a gate check on software quality, 
+- code review has many benefits, but top among them is that it provides a gate check on software quality,
   - it is also a way to share knowledge within a team, improving the redundancy of that team (which is actually a good thing regardless of what corporate types might say!)
   - getting another set of eyes on your code also means you are less likely to flout coding standards and convention
   - there are many different types of code review, and we will explore the most common in this section

   - at a minimum, we want to aim for reproducibility if we are publishing: someone else should be able to take our code and data and run it themselves and get the same result
   - however, for big library packages, we probably want to bump that up to reusable, where our code is easy to use, understand, and modify
 - Documentation is an important part of our code being reusable
   - Even if you write incredibly expressive code, it will not be enough for someone new to start using and modifying your code base
   - How do they install it? Are there any development tools they need? What is the scientific context and limitations of the code?
   - We need to answer all of these questions and more if we want our code to be approachable and reusable

 TODO would be nice to modify the image from <https://the-turing-way.netlify.app/_images/reproducible-definition-grid.svg> so that it better reflects the ACM definition of reproducibility/replicability
