Technical Guide

Technical guides are the deep, mechanism-level explainers for readers who want to understand exactly how something works, not just the steps to set it up — RSS feed anatomy, encoding issues, caching behavior, feed validation, and similar under-the-hood topics. This is the reference tag for troubleshooting content and for anyone building custom tooling around RSS feeds and automated distribution rather than just using an off-the-shelf tool. Recent additions cover team workflows and permissions, what social platform API rate limits mean in practice, how animated images and GIFs survive the trip from feed to network, and finding the feed on less common systems such as Craft CMS. The format is consistent: what the mechanism is, where it breaks, and what to check first when it does. Nothing here assumes you are using any particular tool, because the underlying behaviour is the same whatever reads your feed.
