How We Write About Software

Sources you can check. Facts come from official documentation, vendor pages or standards bodies, and we link to them.
No made-up numbers. If we can’t confirm a figure, it doesn’t go on the page.
Downsides included. Every guide covers the risks and limits, not just the selling points.
Clear money rules. Some future pages may carry affiliate links. Our disclaimer explains how that works.
