 ## Optional themes
 This package ships with optional themes as fixtures, they can be installed using the [loaddata admin command](https://docs.djangoproject.com/en/1.11/ref/django-admin/#django-admin-loaddata). Optional themes are activated on installation.
 
 ##### [Django](https://www.djangoproject.com/) theme (default):
-Run ``python manage.py loaddata admin_interface_theme_django.json``
+Run `python manage.py loaddata admin_interface_theme_django.json`
 
 ##### [Bootstrap](http://getbootstrap.com/) theme:
-Run ``python manage.py loaddata admin_interface_theme_bootstrap.json``
+Run `python manage.py loaddata admin_interface_theme_bootstrap.json`
 
 ##### [Foundation](http://foundation.zurb.com/) theme:
-Run ``python manage.py loaddata admin_interface_theme_foundation.json``
+Run `python manage.py loaddata admin_interface_theme_foundation.json`
 
 ##### [U.S. Web Design Standards](https://standards.usa.gov/) theme:
-Run ``python manage.py loaddata admin_interface_theme_uswds.json``
+Run `python manage.py loaddata admin_interface_theme_uswds.json`
 
 ### Add more themes
 You can add a theme you've created through the admin to this repository by [sending us a PR](http://makeapullrequest.com/). Here are the steps to follow to add:
 
 1. Export your exact theme as fixture using the `dumpdata` admin command:
-``python manage.py dumpdata admin_interface.Theme --indent 4 -o admin_interface_theme_{{name}}.json --pks=N``
+`python manage.py dumpdata admin_interface.Theme --indent 4 -o admin_interface_theme_{{name}}.json --pks=N`
 
 2. Copy the generated json file into the fixtures folder *(making sure its name starts with* `admin_interface_theme_` *to avoid clashes with fixtures that might be provided by other third party apps)*.
 
-3. Remove the `"pk"` from the fixture and make sure the `active` field is set to `true` *(in this way a theme is automatically activated when installed)*.

 4. Edit the section above to document your theme.

+### Custom `base-site.html`
+> I already have a custom `base_site.html`, how can I make it work?
 
 You can use [django-apptemplates](https://github.com/bittner/django-apptemplates), then add `{% extends "admin_interface:admin/base_site.html" %}` to your `base_site.html`
 
+### Language Chooser not showing
+> I have enabled the **Language Chooser**, but it is not visible in the admin, what should I do?
+
+You must configure multilanguage `settings` and `urls` correctly:
+```python
+LANGUAGES = (
+    ("en", _("English")),
+    ("it", _("Italiano")),
+    ("fr", _("Français")),
+    # more than one language is expected here
+)
+LANGUAGE_CODE = "en"
+USE_I18N = True
+MIDDLEWARE = [
+    # ...
+    "django.middleware.locale.LocaleMiddleware",
+    # ...
+]
+```
+
+```python
+from django.conf.urls.i18n import i18n_patterns
+from django.contrib import admin
+from django.urls import include, path
+
+# ...
+
+urlpatterns = [
+    path("i18n/", include("django.conf.urls.i18n")),
+]
+urlpatterns += i18n_patterns(path("admin/", admin.site.urls))
+```
