What is the primary audience consideration when writing a developer onboarding guide?
Onboarding docs are written for someone with zero context about the specific codebase and team. Every implied step or unexplained term is a potential blocker for a new joiner.
2 / 29
Which element is most important to include in an environment setup guide?
Setup guides must be executable. Every step needs the exact command, and ideally shows what successful output looks like so the reader knows whether the step worked.
3 / 29
What does 'the 30-60-90 day plan' structure in onboarding documentation describe?
A 30-60-90 day plan sets expectations: 30 days = learning the codebase and process; 60 days = making small contributions; 90 days = owning a feature or area. It gives new joiners a clear ramp-up path.
4 / 29
How should you document a 'known issue' in a setup guide?
Known issues that new joiners hit repeatedly should be documented with symptoms, workarounds, and context. This saves hours of debugging time and shows the team is maintaining the docs.
5 / 29
What is 'evergreen documentation' in the context of onboarding?
Evergreen docs stay current. Teams often achieve this by linking docs to the code review process (docs updated when related code changes), assigning doc owners, or scheduling periodic reviews.
6 / 29
Which sentence best opens the 'Architecture Overview' section of an onboarding guide?
A good architecture overview names the components, explains what each does in one sentence, and describes how they relate. This gives a new joiner a mental model before diving into code.
7 / 29
What is the purpose of a 'Glossary' section in onboarding docs?
Every team uses internal shorthand — project codenames, abbreviations, service nicknames. A glossary prevents new joiners from being blocked by unfamiliar terms in meetings and documentation.
8 / 29
What does 'doc rot' refer to in documentation management?
Doc rot (documentation rot) is the decay of documentation accuracy over time. Outdated onboarding docs are particularly harmful because they waste new joiners' time and erode trust in documentation.

Sarah posted this message in the #devs Slack channel after reviewing a PR:
"This code doesn't use any of our preferred logging libraries. It also lacks clear error handling. Please update to follow the logging guidelines and add try/catch blocks for potential exceptions."
Which phrase best describes Sarah's intention in this comment, focusing on how it relates to onboarding documentation?
A To simply list all the technical requirements for the code change.
B To provide a detailed walkthrough of the codebase and explain its functionality.
C To direct the developer to existing documentation (the 'logging guidelines') and ensure they understand expected standards.
D To offer technical support and assist with debugging the code directly.
Sarah's comment isn't about providing a full explanation of the code itself (option B). Instead, she is pointing the developer to relevant existing documentation – the 'logging guidelines' – and highlighting the importance of adhering to established standards. This demonstrates how onboarding documentation should guide developers towards *where* to find information, rather than simply repeating technical details they likely already know. Option A is too broad; option D focuses on a specific task (debugging) rather than the broader goal of guiding adherence to best practices.

PR Description:
"This new feature implements the user profile update endpoint. The API uses RESTful conventions and expects a JSON payload with 'firstName', 'lastName', and 'email' fields. Error responses will be returned as 400 Bad Request if the input is invalid."The correct answer emphasizes clarity of purpose and outlining key elements for onboarding. A new developer needs to quickly understand *why* this PR exists and what it does, alongside any critical details like error handling – these are foundational pieces of documentation that directly support the learning process. Options A and C are too detailed and assume prior knowledge; option D is irrelevant to the documentation's core role in onboarding.

Ben posted this update during the daily standup: 'I've finished implementing the new authentication flow. I'm documenting it in detail for the onboarding docs, focusing on how to integrate with our existing identity provider.' Considering Ben's statement and the goal of effective onboarding documentation, which phrasing best captures his primary focus?Ben's statement highlights the critical importance of focusing onboarding documentation on *integration*, specifically connecting new components to established systems. This aligns directly with the core goal of onboarding: enabling developers to quickly become productive by demonstrating how their work fits into the broader architecture. Options A and B are too broad, while option D misses the crucial connection aspect vital for new users. The correct answer emphasizes that integration is the most immediate need for a new developer.

During a code review, Liam comments on a PR with the following text: 'This component doesn't adhere to our established naming conventions. Please rename all variables and methods using camelCase.' Considering Liam's comment within the context of onboarding documentation, which option best reflects his primary intention?
Liam's comment isn't simply about fixing a bug; it's directing the developer to understand and follow project standards. This aligns perfectly with onboarding documentation's goal of teaching best practices and ensuring consistency across the codebase. Option A is irrelevant as test coverage wasn't the focus, B misinterprets the intention, and D focuses on immediate troubleshooting rather than foundational guidance – a key component of effective onboarding.

You're writing documentation for a new microservice that handles user authentication. A junior developer asks: 'I need to know what happens if a user enters an invalid email address during registration.' What's the *most* important information you should include in the documentation to help them understand the system's response?
Understanding the *response* to invalid input is crucial for developers. Error codes provide immediate feedback on what went wrong and how to correct it – this directly aids in troubleshooting and onboarding. While other elements are important, error handling details are paramount for a new developer.
