+## Multilanguage support
+
+insight use [angular-gettext](http://angular-gettext.rocketeer.be) for
+multilanguage support. 
+
+To enable a text to be translated, add the ***translate*** directive to html tags. See more details [here](http://angular-gettext.rocketeer.be/dev-guide/annotate/). Then, run:
+
+```
+grunt compile
+```
+
+This action will create a template.pot file in ***po/*** folder. You can open
+it with some PO editor ([Poedit](http://poedit.net)). Read this [guide](http://angular-gettext.rocketeer.be/dev-guide/translate/) to learn how to edit/update/import PO files from a generated POT file. PO file will be generated inside po/ folder.
+
+If you make new changes, simply run **grunt compile** again to generate a new .pot template and the angular javascript ***js/translations.js***. Then (if use Poedit), open .po file and choose ***update from POT File*** from **Catalog** menu.
+
+Finally changes your default language from ***public/src/js/config*** 
+
+```
+gettextCatalog.currentLanguage = 'es';
+```
+
+This line will take a look at any *.po files inside ***po/*** folder, e.g.
+**po/es.po**, **po/nl.po**. After any change do not forget to run ***grunt
+compile***.
+
+
 ## Note
 
 For more details about the *insight API* configs and end-point, just go to [insight API github repository](https://github.com/bitpay/insight-api) or read the [documentation](https://github.com/bitpay/insight-api/blob/master/README.md)
