+Open-Falcon support zh_CN by default. Any translation will be appreciated.
+
+If you want to translate open-falcon to a new language or just refine the exist translation, you could follow the instructions below.
+
+## refine the exist translation
+
+1. find what you want to translate in the source code and replace it to `{{_('xxx')}}`.
+2. run `python ./scripts/tr_update.py`, it will update `rrd/translations/foo/LC_MESSAGES/messages.po`.
+3. run `python ./scripts/tr_compile.py`, it will generate a complied file in `rrd/translations/foo/LC_MESSAGES/messages.mo`
+
+
+## create a new language(such as Spanish support)
+1. update `rrd/config.py`, add a new key to `LANGUAGES`, such as:
+    
+        LANGUAGES   = {
+            'en':  'English',
+            'zh_CN':  'Chinese-Simplified',
+            'es': Spanish,
+        }
+    
+2. run `python ./scripts/tr_init.py`, it will update `rrd/translations/es/LC_MESSAGES/messages.po`.
+3. find what you want to translate in the source code and replace it to `{{_('xxx')}}`.
+4. run `python ./scripts/tr_update.py`, it will update `rrd/translations/es/LC_MESSAGES/messages.po`.
+5. run `python ./scripts/tr_compile.py`, it will generate a complied file in `rrd/translations/es/LC_MESSAGES/messages.mo`
