+### The TypeDefs I need to reference are not in node_modules/@types

+By default `ember-cli-typescript` loads up any type defs found in node_modules/@types. If the type defs you need are not found here you can register a custom `path` in the tsconfig.json file

+{
+  "compilerOptions": {
+    "paths": {
+      "welp/*": ["app/*"],
+      "redux": ["node_modules/redux/index.d.ts"]
