- Redactor

First, add a link to Redactor's translation on a page, for example for Finnish language:

<script src="/your-folder/fi.js"></script>

Then create a file with the plugin translation and connect it to the page too:

<script src="/your-folder/plugins/myplugin.fi.js"></script>

In the plugin's translation file, call the $R.addLang function to add the object with the language variables to the Redactor's translation. For example:

$R.addLang('fi', {
    "table": "Taulukko",
    "insert-table": "Lisää taulukko"
});

That's all. Now gathering everything.

        lang: 'fi'
     });
