The Millettarian Methodology is an omnidoxical document organised as a non-disquisitional part of the Omnidoxy and is featured as the ninth segment of the Appendix of the Omnidoxy. It addresses a vast range of subjects, each of which is ascribed a particular methodology. Some of these subjects include public relations, economics, politics, governance, business management, and accounting.

One of the most important functions of The Millettarian Methodology is its introduction to Millettarianism as the ideological branch of Astronism. The Millettarian Methodology is considered to be one of the founding documents of Astronic ideology and forms the foundations of much of how The People's Constitutional Company of Jesse Millette and The Institution of The Philosophy of Millettism are expected to practically operate in various spheres.

Much criticism has been directed towards The Millettarian Methodology since its publication as part of the Original Cometanic Edition of the Omnidoxy. The majority of such criticism resides in the notion that The Millettarian Methodology remains incomplete and without sufficient elaboration of its ideas. This has been addressed by its author, Cometan, who insists that the elaboration of The Millettarian Methodology will take place in post-omnidoxical works.
