+## Localization
+
+Discord Slash Commands support name/description localization. Localization is available for names and descriptions of Slash Command Groups ([GroupAttribute]), Slash Commands ([SlashCommandAttribute]), Slash Command parameters and Slash Command Parameter Choices. Interaction Service can be initialized with an `ILocalizationManager` instance in its config which is used to create the necessary localization dictionaries on command registration. Interaction Service has two built-in `ILocalizationManager` implementations: `ResxLocalizationManager` and `JsonLocalizationManager`.
+
+### ResXLocalizationManager
+
+`ResxLocalizationManager` uses `.` delimited key names to traverse the resource files and get the localized strings (`group1.group2.command.parameter.name`). A `ResxLocalizationManager` instance must be initialized with a base resource name, a target assembly and a collection of `CultureInfo`s. Every key path must end with either `.name` or `.description`, including parameter choice strings. [Discord.Tools.LocalizationTemplate.Resx](https://www.nuget.org/packages/Discord.Tools.LocalizationTemplate.Resx) dotnet tool can be used to create localization file templates.
+
+### JsonLocalizationManager
+
+`JsonLocaliationManager` uses a nested data structure similar to Discord's Application Commands schema. You can get the Json schema [here](https://gist.github.com/Cenngo/d46a881de24823302f66c3c7e2f7b254). `JsonLocalizationManager` accepts a base path and a base file name and automatically discovers every resource file ( \basePath\fileName.locale.json ). A Json resource file should have a structure similar to:
+
+```json
+{
+    "command_1":{
+        "name": "localized_name",
+        "description": "localized_description",
+        "parameter_1":{
+            "name": "localized_name",
+            "description": "localized_description"
+        }
+    },
+    "group_1":{
+        "name": "localized_name",
+        "description": "localized_description",
+        "command_1":{
+            "name": "localized_name",
+             "description": "localized_description",
+             "parameter_1":{
+                 "name": "localized_name",
+                  "description": "localized_description"
+            },
+            "parameter_2":{
+                 "name": "localized_name",
+                  "description": "localized_description"
+            }
+        }
+    }
+}
+```
