How we choose links

Useful sources for a specific task.

We prioritise standards owners, official documentation, established industry bodies and practical tools that help with a specific task. Check software compatibility, licence terms and project suitability before using any external resource.

Dynamic tools, pricing and compatibility should be checked at least quarterly; standards and stable guidance annually or when a replacement edition appears.
