How to translate Jolomea using Jolomea
You can only follow this tutorial if you have installed at least Jolomea 0.0.4.
Click on Components=>Jolomea
Click on the "Joomla Back" submenu (because, at the moment, the component is only located in the backoffice).
Select your target language. This is your language.
Select the source language (usually, it will be english).

Find the com_jolomea entry in the array.
Click on Edit Translation.

Localize the jolomea keys.

I you click on the suggest button, you will get a Google Translate suggestion.
After you have finished to translate, you have the choice (at the moment, it is only available for the localization of the jolomea component).
Either you click on "save", if you just want to save your work, or you can click on "Save and share" if you also want to share the translations you have just made. This way, your job will be included in the next release of Jolomea.
The documentation is still in progress. Sorry for that...
