# Welcome to the Commonway System

This is the first post on what will be an ongoing record of how the Commonway System gets built: research notes, structural decisions, new patterns as they're added, and the occasional correction when something earlier turns out to be wrong.

If you're new here: Commonway System is a pattern language for roads and streets, a reference guidebook organized by Functional Classification and Street Typology, with every prescriptive claim traced back to a cited source wherever one exists. Start with the [Guide](https://commonwaysystem.org/guide.md) if you want to understand how the system is put together, or the [Patterns](https://commonwaysystem.org/patterns.md) section if you want to jump straight to a specific kind of street.

This blog isn't part of the guidebook itself, it won't carry prescriptive claims or citations the way a pattern page does. It's the place for everything adjacent to the guidebook: why a decision was made, what changed and when, what's coming next. The [Release History & Roadmap](https://commonwaysystem.org/about/release-history.md) page remains the authoritative changelog; this is more room to explain the reasoning behind it.

More to come.
