+# MMP Module Manager
+
+- _aka_ MMM _aka_ M3 (official-est name)
+
+A CLI Tool to automagically manage your modules.
+
+(no more manually `git clone`-ing dependencies!)
+
+<!-- Upon further inspection, this idea is shit
+# Specification vs Implementation
+
+Some call it a bug, but I call it (either) a revoluionary (or stupid) idea.
+
+Instead of just writing a _package_, what you might do in other scenarios. You write a specification.
+
+Nothing formal, it can be just a markdown file or, if you want to get more fancy, a [d.ts type definition](https://www.typescriptlang.org/docs/handbook/declaration-files/templates/module-d-ts.html).
+
+But then, modules, packages, libraries, whatever you want to call them (modules, in this case) are identified (imported by other modules/packages/libraries) by their specification, not their implementation.
+
+`ddg.chat`, the semi-official (made by Dinhero Development Group, the same people who made MMP, the module loader) chat library, is then the specification that defines how a chat library should behave.
+
+`ddg.chat`, instead of declaring how chat parsing should be implemented (by analyzing the downstream `chat_message` and `chat_command` packets), declares how a chat library should interface and expose itself to the rest of the ecosystem (there should be a default exported object that has `writeDownstream` and `writeUpstream` functions ...)
+
+This allows you to mix and match implementations, as long as they share the same specification.
+
+I don't really see any real-world use for this aside from person A creating a module, deprecating/archiving/abandoning it and person B creating an equivalent better module.
+
+Things like this happen all the time in other ecosystems and are usually referred to as "spiritual successors". So my idea might not be so revolutionary after all.
