What you may do
You may view and print pages for your own reference. That covers reading a service page before a call, saving a technology note for a colleague, or printing a page to mark up while you plan a project.
What needs permission
You may not reproduce, distribute, or use the content for commercial purposes without our prior written permission. Re-publishing our text, reusing our layouts or images in another site, or reselling our material as part of a service are the cases this covers. Write to us and we will tell you whether a specific use is fine.
Ask first — it is usually a short answer.
