Documentation Standards
Software outlives the team that wrote it, and documentation decides whether the next team can work with it. Renvric writes documentation as a deliverable with owners, templates and review, covering decisions, architecture, operations and use, kept close to the code it describes.

Documentation people actually use
Most documentation fails because it is written once, stored far from the code and never updated. Renvric aims for fewer, better documents: each with a purpose, an audience and an owner, and each stored where the people who need it will look. Out-of-date documents are treated as defects.
The core set of documents
Architecture overview
The main components, how they interact, where data lives and the reasons behind major choices, often drawn with a model such as C4.
Architecture decision records
Short entries capturing a decision, the alternatives considered and the consequences, dated and numbered.
API reference
Generated from the code or a specification such as OpenAPI, so it matches reality, with examples for common calls.
Runbooks
Step-by-step procedures for deployment, restore, rotation of credentials and common incidents.
Setup guide
How a new developer builds, runs and tests the project from a clean machine.
User and administrator guides
Task-based instructions for the people who use or configure the product.
Standards for writing
- Write for a named reader, such as a new engineer or a support analyst, and state who that is.
- Lead with what the reader needs to do, then explain why.
- Use plain language, define terms once and keep examples realistic.
- Prefer diagrams for structure and text for reasoning, with diagram source files stored alongside.
- Keep each document short enough to maintain; link to detail instead of duplicating it.
Share the outcome you need and Renvric will recommend the smallest useful next step.
Where it lives and how it stays current
Technical documentation is kept in the repository as versioned text, reviewed in the same pull request as the code change that affects it. Consider an API endpoint whose behaviour changes: the specification, the example and the changelog update together, and the reviewer checks them. Client-facing guides live in a shared knowledge base agreed at onboarding.
The definition of done includes documentation, so work is not accepted without it.
Roles
- Engineers write and update technical documents as part of their work.
- The technical lead owns the architecture overview and decision records.
- The delivery lead keeps project artefacts such as the risk register, decision log and release notes.
- The client reviews user-facing material for accuracy and tone and confirms where it must be stored.
A test of quality
A useful check is to ask someone new to the project to follow the setup guide and a runbook without help. Where they stumble, the documentation is repaired. Clients can run the same exercise before handover to confirm that they could operate the system without the original team.

Common questions
Who are documentation standards for?
Clients who will operate or extend the system, internal engineering teams taking over code, and auditors or procurement teams assessing maintainability. They also help new Renvric team members join a project quickly.
What do you need from us?
Tell us who will read the documentation, what tools you already use for knowledge management, any templates your organisation requires, and whether documents must be reviewed or approved by security, compliance or architecture groups.
Who owns the documentation we pay for?
Ownership and licence terms are set out in your agreement. Our practice is to deliver documentation in editable formats, stored in your repositories or knowledge base, so you can maintain it without depending on us.
How do you keep it from going stale?
By making it part of the definition of done and the review process. Documentation changes are included in the same change as the code, API references are generated where possible, and handover includes a check that new readers can follow the guides.
Who can answer a related question?
Email info@renvric.com. Questions on documentation format and tooling go to a technical lead, and requests for sample documents are handled by the engagement lead, subject to confidentiality. Tell us which systems are involved and who will inherit them, so the right person can speak to the documentation you will need.
Keep exploring
Ask for a sample of an architecture decision record, a runbook and an API reference, and ask who is responsible for keeping them current. Intellectual property and ownership of documentation are stated in your contract.
