Technical Documentation in St Asaph
Writing down how a St Asaph business's systems actually work, so the knowledge stops living in one person's head. Architecture notes, API references, runbooks and handover packs — written for the person who will need them at two in the morning without the author available.
Why this comes up
The problem
Undocumented systems make every change slow and every departure expensive. The person who knows how it works is also the person too busy to write it down, which is exactly why it never gets written.
What you get
What we deliver
- Architecture documentation explaining what exists and, more usefully, why it is that way
- API reference generated from the code where possible, so it cannot drift out of date
- Runbooks for recurring operational tasks, written to be followed under pressure
- Onboarding guide that gets a new developer productive without shadowing someone for a fortnight
- Decision records capturing the reasoning behind choices that will otherwise be questioned annually
- Documentation kept beside the code, so updating it is part of a change rather than a separate task

Technical Documentation in St Asaph — common questions
- Does documentation not go stale immediately?
- Documentation kept somewhere separate does. Kept in the repository, reviewed alongside the code and generated from the source where possible, it stays current because updating it is part of the change rather than an afterthought nobody is measured on.
- What is worth documenting?
- Reasoning and operations. What the code does is readable from the code; why a decision was made is not, and neither is what to do when a job fails at 3am. Documenting the obvious is what gives documentation its reputation.
- Our only expert is leaving next month. Can you capture it in time?
- Usually yes, and it is a common trigger. The work is structured interviews plus reading the system alongside them, prioritising the things only they know over the things anyone could work out.
- Who is it written for?
- Agreed before we start, because it changes everything. A runbook for an on-call engineer, an integration guide for an external developer and a handover for a new supplier are three different documents.
- Do you work with businesses across Denbighshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including St Asaph and the surrounding Denbighshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of St Asaph businesses do you usually work with?
- Precision manufacturing and R&D systems for the technology park, alongside basic tooling for a very small local trade base. Beyond that we work across Optoelectronics, Manufacturing, Healthcare, Agriculture and Retail.
- Do you cover the areas around St Asaph?
- Yes — we work throughout Wales, including Chester, Bangor, Wrexham. St Asaph is an urban area of roughly 3,500+, and we take on work across the wider Denbighshire region rather than the city boundary alone.
