# General/Collaboration

## Collaboration

### Definition of Done

We suggest you use a Definition of Done for your project. This gives everyone in the team an understanding when a task is *really* done.

You can find the CorrelAid Definition of Done here:

## General best practices

Those general best practices should help you with implementing the items of the Definition of Done.

### **How to document code**

Documenting your code should always be less about the "what" and more about the "why". However, if you are writing code which might be a bit more advanced/complex, adding some comments about *how* it works is also useful, especially for the less experienced team members.

### **Peer review**

Peer reviewing someone else's code involves three things:

1. test the code on your machine
2. provide feedback (possibly suggesting changes)

Whenever the skills of the team allow for it, you should use [branches](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-branches) and [pull requests](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests) for this. [Pull request reviews](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/reviewing-changes-in-pull-requests/about-pull-request-reviews) are a great way to directly suggest changes.

If a team member is still quite new to Git, a file-driven "review process" (e.g. `data_cleaning_jack.R`) is also acceptable as to not overwhelm them with Git. You can leave comments in the file and commit it back to Git or discuss your feedback in a GitHub issue. Always be kind to team members with less experience.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.correlaid.org/projects/project-team/best-practices/collaboration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
