+## Internationalization (i18n)
+
+To make your plugin multi-language you can use `HFS.t` function in javascript, like this: `HFS.t("Hello!")`.
+Now, to add translations, you'll add files like `hfs-lang-XX.json` to your plugin (same folder as plugin.js),
+where XX is the language code. The system is basically the same used to translate the rest of HFS,
+and you can [read details here](https://github.com/rejetto/hfs/wiki/Translation).
+
+In the previous example "Hello!" is used both as key for translation and as for default text.
+If you want to separate these 2 things, just pass 2 parameters, key and default text. Eg: `HFS.t('greeting', "Hello!")`.
+
+If you need to pass variables in the text, introduce a third parameter in the middle.
+Eg: `HFS.t('filter_count', {n:filteredVariable}, "{n} filtered")`
