 As each Node LTS version reaches its end-of-life we will remove that version from the `node` `engines` property of our package's `package.json` file. Removing a Node version is considered a breaking change and will entail the publishing of a new major version of this package. We will not accept any requests to support an end-of-life version of Node. Any merge requests or issues supporting an end-of-life version of Node will be closed.
 
 We will accept code that allows this package to run on newer, non-LTS, versions of Node.

+## Project History
+
+The project was started by @bergie in 2012 based on Michael Bosworth's [express-saml](https://github.com/bozzltron/express-saml) library. From 2014 - 2016, @ploer served as primary maintainer.
+@markstos served the primary maintainer from 2017 till 2020 when he created the node-saml organization. With a goal to create a team of maintainers, invitations were sent to major contributors and fork authors to work together to maintain all the improvements in one place.
+
+Since 2020, @cjbath emerged as the primary maintainer, with major contributions from @gugu and @zoellner. Major updates from the team included rewriting the project in TypeScript and splitting off a `node-saml` module which can be used without Passport. Almost 100 other developers have contributed improvements to the project.
+
+The project continues to be maintained by volunteers. Contributions small and large are welcome.
