Please run npm run lint to fix some code convention errors :) I'll update the readme file to provide some hints regarding contributions.

Unfortunately it fails two tests:

` FAIL test/parsers/templateParser.spec.js ? parsers › templateParser › should connect resource and dependency

TypeError: Cannot read property 'name' of undefined

  at Object.it (test/parsers/templateParser.spec.js:127:47)

  at process._tickCallback (internal/process/next_tick.js:188:7)

FAIL test/reducers/fileDialog.spec.js ? reducers › fileDialog › should handle OPEN_FILE

expect(value).toMatchSnapshot()

Received value does not match stored snapshot 1.

`

while the second one we can mitigate, the first one has to be fixed.
