How the articles work
Guides and essays
Articles offer practical ways to observe a situation, compare choices and decide what to check next. Examples explain a method; they are not accounts of an interview, product test or commissioned visit.
Sources
External guidance is linked where it supports a specific point. Check the current requirements for your location, equipment or project before acting on advice that depends on them.
Photographs and corrections
Photo credits link to the photographer’s original page and licence. For a correction, identify the article and passage and include a supporting source. For an image enquiry, include its credit.
