+start the dual servers (dapp + mascara)
+```
+node server.js
+```
+
+open the example dapp at `http://localhost:9002/`
+
+*You will need to build MetaMask in order for this to work*
+```
+gulp dev
+```
+to build MetaMask and have it live reload if you make changes
+
+
+## First time use:
+
+- navigate to: http://127.0.0.1:9001/popup/popup.html
+- Create an Account
+- go back to http://localhost:9002/
+- open devTools
+- click Sync Tx
+
+### Todos
+- Look into using [Service Workers](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API)
