@valtlait you'll also need to add a file src/nls/fi/urls.js so that we can pick up the getting started content. See the french directory for an example. I've gone ahead and filled in the appropriate Finnish URLs below.

define({
    // Relative to the samples folder
    "GETTING_STARTED"           : "fi/Aloitus",
    "ADOBE_THIRD_PARTY"         : "http://www.adobe.com/go/thirdparty_fi/",
    "WEB_PLATFORM_DOCS_LICENSE" : "http://creativecommons.org/licenses/by/3.0/deed.fi"
});

Looks good. There's one minor change to enable the getting started project. I'll do that separately. Thanks @valtlait.

@jasonsanjose, seems like this translation of the sample project is missing the screenshot directory and graphic.

[jasonsanjose]

Thanks. I'll file a bug.
