How to localize?

[cod3rshotout]

I was able to run your SEO package and it's working well. But I don't understand how can I translate it in my language. I tried to set the language using the following:

const paper = new Paper(this.text, {
            keyword: this.keyword,
            title: this.title,
            description: this.description,
            url: this.url,
            metaDescription: this.metaDescription,
            titleWidth: this.titleWidth,
            locale: 'it_IT'
            permalink: this.permalink
        });

I also tried to set the locale only to it, but same issue. The generated SEO content is still in english.
I saw that there is that object:

i18n() {
    return new Jed({
        domain: `js-text-analysis`,
        locale_data: {
            "js-text-analysis": { "": {} }
        }
    })
}

but I don't understand if I need to provide the strings to translate, and if so, where should I find those strings.

Could you help me please?

Thanks
