+[react-redux-polyglot](https://github.com/Tiqa/react-redux-polyglot) use [redux-polyglot](https://github.com/Tiqa/redux-polyglot) as main dependency, so we work on a [dev branch](https://github.com/Tiqa/redux-polyglot/tree/dev) for staging and need to follow this __3 principles__ :
+- this branch must be as clean as master, so `npm run prepublish` must be ok.
+- all master merges should be tagged by a new version. (on the master branch only)
+- all change must be validated by [react-redux-polyglot](https://github.com/Tiqa/react-redux-polyglot) unit testing before merge on master
