+# Module System
+
+ES6 Modules just dont work *well* with `RiotJS <=3`. You cannot import them in your web componets script tag, you could include them at the top of the page, but that requries a build-*watch*-proccess that goes against my goal -- **zero-build** develop process!
+
+**Mixins** is Riots answer to shared / resultable componet logic, but I needed another level to easily compose larger bits of logic before they were injected into  `riot.mixin`, that is where `require1k` comes in.  It is a **zero-build** CommonJS/NodeJS version of `require` that lended to my love of NodeJS server-sed development, but on the client.
+
+**Require1k** While nearly perfect, there is a couple grips I do have:
+
+    - `.js` implied.  I like to be specific and include `.js` when requiring files
+    - defaults to `node_module` lookup.  I just want to require a path to my file
+
+So, in the future I will probally look at forking `require1k`, but for now, for 1k dependency this is pretty awesome!
