see TODO.md file

if you want to sychronize your data, you need to install and configure a CouchDB

• how to install couchdb and futon on ubuntu 14 04
• how to install couchdb on a RaspberryPI - Raspbian Jessie

when you done this and login to Futon, create following databases

• *couchdb-databbase-prefix-*group
• *couchdb-databbase-prefix-*todo

then configure your app in

menu -> Database -> Sync to CouchDB

choose somthing clear as prefix like my-fxos-todo-app- or leave this blank if you don't wan't to use your CouchDB for something else

npm install
gulp build

and run a webserver

npm run http

then click on http://127.0.0.1:8000

to develop on the service worker offline stuff

npm run chrome
npm run https
gulp build --no-appcache

then click on https://127.0.0.1:8000

if you want to work on the synchronization and need to debug in your Chrome browser, you need to enable CORS in your CouchDB

github.com/pouchdb/add-cors-to-couchdb

CouchDB doesn't come with CORS enabled by default. This is a problem for libraries like PouchDB, which depend on being able to access CouchDB ...
