+# Firebase Functions Deployment
+
+Firebase functions deploy from a node.js app (_I think_). This means that your
+changes won't propagate unless you deploy them to the server.
+
+In order to deploy Firebase apps from your machine, you must first install the
+packages needed.
+
+```
+$ npm install firebase firebase-functions firebase-admin
+```
+
+Once installation is complete, you can deploy to the firebase functions.
+
+```
+$ firebase deploy --only functions:<NAME_OF_FUNCTION>
+```
+
+More to come as we learn how this works...
