+Using custom locales
+====================
+
+Personalized translations go into the `config/custom_locales/` directory.
+Custom locales can be identified by the rails environment, schema name in a
+multitenancy setup or domain name until the first dot (e.g env1.coop.br for the
+example below).
+
+Currently, the only filename prefix for the localization file which is
+processed is "environment". For instance, a POT file would be called
+"environment.pot".
+
+The structure of an environment named env1 with custom translations for both
+Portuguese and Spanish and an environment named env2 with custom Russian
+translation would be:
+
+    config/
+      custom_locales/
+        env1/
+          environment.pot
+          pt/
+            environment.po
+          es/
+            environment.po
+        env2/
+          environment.pot
+          ru/
+            environment.po
