+# Wagtail modeltranslation
+(based on https://github.com/deschler/django-modeltranslation)
+
+Simple app containing a mixin model that integrates modeltranslation
+(https://github.com/deschler/django-modeltranslation) into wagtail panels system.
+
+![alt tag](https://github.com/infoportugal/wagtail-modeltranslation/blob/master/screenshot.png?raw=true)
+
+## Quick start
+
+1. Make sure you have django-modeltranslation installed:
+
+        pip install django-modeltranslation
+
+2. Add "wagtail_modeltranslation" to your INSTALLED_APPS setting like this:
+
+        INSTALLED_APPS = (
+            ...
+            'wagtail_modeltranslation',
+            'modeltranslation',
+            ...
+        )
+
+3. Use TranslationMixin in order to integrate django-modeltranslation with Wagtail admin. ** IMPORTANT: ** make sure that TranslationMixin is declared before Page class on model inheritance. Like following:
+
+        from wagtail_modeltranslation.models import TranslationMixin
+        class FooModel(TranslationMixin, Page):
+            foo = models.CharField()
+        FooModel.panels = [...]
+
+4. Visit django-modeltranslation for documentation on how to implement translation fields: http://django-modeltranslation.readthedocs.org/en/latest/
+
+5. In order to update pages url_path field use **"set\_translation\_url\_paths"** instead of original "set\_url\_paths"
+
+6. Use **"change_lang"** template tag to fetch translated urls based on translated slugs:
+
+        {% load modeltranslation %}
+        <li class="dropdown">
+            <a data-toggle="dropdown" class="dropdown-toggle" data-hover="dropdown" href="#">{{ LANGUAGE_CODE }}<i class="fa fa-angle-down ml5"></i></a>
+            <ul class="dropdown-menu" id="language-dropdown">
+                {% for lang in languages %}
+                {% if lang.0 != LANGUAGE_CODE %}
+                <li tabindex="-1"><a href="{% change_lang lang.0 %}">{{ lang.1 }}</a></li>
+                {% endif %}
+                {% endfor %}
+            </ul>
+        </li>
