# Cosyte Developer Documentation

> Developer documentation for the Cosyte open-source healthcare interoperability packages, published on npm under the `@cosyte` scope. Each entry under Packages links to that package's current documentation entry point on this site.

Every link here is an absolute production URL. A package link serves the newest released version of that package's documentation; superseded version URLs are deliberately absent, as is any package that has not published documentation yet.

Every documentation page is also published as plain Markdown at its own URL with `.md` appended. The Full text section links the complete current documentation as Markdown: one file for the whole site, and one per package.
