+# @sern/localizer
+
+A localization module for managing translations and providing localized content in your application.
+
+## Installation
+
+```
+npm i @sern/localizer
+```
+
+## Usage
+
+**Initializing the Localizer**
+```ts 
+import { makeDependencies } from '@sern/handler';
+import { Localization } from '@sern/localizer';
+
+await makeDependencies(({ add }) => {
+    add('localizer', Localization());
+});
+```
+This localizer is **FILE BASED**.
+Create the directory `assets/locals`. Each json file in here must be named after the `locale`
+
+import { Tabs, TabItem } from "@astrojs/starlight/components";
+
+<Tabs>
+  <TabItem label="Spanish">
+    ```json title=~/assets/locals/es.json
+        {
+            "salute": {
+                "hello": "hola"
+            }
+        }
+    ``` 
+  </TabItem>
+  <TabItem label="English">
+    ```json title=~/assets/locals/en-US.json
+        {
+            "salute": {
+                "hello": "hello"
+            }
+        }
+    ``` 
+  </TabItem>
+</Tabs>
+
+
+
+**Accessing translations**
+- If you are in a command execute callback, use `deps` from SDT.
+```ts 
+execute : (ctx, { deps }) => {
+    //the localizer object from makeDependencies
+    deps.localizer
+    // Returns the Spanish translation for 'salute.hello'
+    deps.localizer.translate("salute.hello", "es"); 
+}
+```
+
+
+```ts
+import { local } from '@sern/localizer';
+
+// Returns the Spanish translation for 'salute.hello'
+const greeting = local('salute.hello', 'es'); 
+```
