Puppet RFC
Puppet RFC Repository
This repository contains Puppet RFCs, which are "Requests For Comments" in the tradition of the IETF RFC process. They are proposals to enhance / add features to Puppet or something in the Puppet ecosystem. This is a community-focused process intended to improve openness and transparency in both Puppet Labs-funded and contributor efforts. For details, please read PRFC-0, which describes the rationale and process.
Historical note
From their introduction in 2013 until a renaming/reboot in mid-2015, the process and artifacts were called "Armatures", abbreviated to "ARMs". While the git repository and all current documentation are updated, it's possible you will see references to the old name in immutable artifacts like mailing list threads, bug tracker tickets, etc.
