 Add this config to your horizon `local_settings.py`
 
-```bash
+```python
 YUYU_URL="http://yuyu_server_url:8182"
 CURRENCIES = ('IDR',)
 DEFAULT_CURRENCY = "IDR"
 ```
 
 Then restart Horizon.

+## Multi Region
+
+If your openstack using multiple region, and each region have its own Yuyu server, you can specify Yuyu server URL for each region.
+
+To do that, you can add `YUYU_URL_REGION` to horizon `local_settings.py`
+
+`YUYU_URL_REGION` is a list of tuples which define a mapping from region name (as in horizon `AVAILABLE_REGIONS`) to Yuyu URL for each. The tuple format is ***('{{ region_name }}', 'http://{yuyu_url}')***.
+
+For example:
+
+```python
+# Example AVAILABLE_REGIONS settings
+
+AVAILABLE_REGIONS = [
+    ("https://172.12.12.10:5000/v3", 'US'),
+    ("https://172.12.12.11:5000/v3", 'Singapore')
+]
+
+# Set Yuyu URL for each region
+YUYU_URL_REGION = [
+    ('US', 'http://region_a_yuyu_server_url:8182'),
+    ('Singapore', 'http://region_b_yuyu_server_url:8182'),
+]
