 #### Get the code ready
 Optionally, you can use a default value for the keys. The syntax is `key@@[default value]`:
 ```html
-<p>{t('app.title@@Qwik Speak'}</p>
-<p>{t('home.greeting@@Hi! I am {{name}}', { name: 'Qwik Speak' })}</p>

+<p>{t('greeting@@Hi! I am {{name}}', { name: 'Qwik Speak' })}</p>
 
 ```
 When you use a default value, it will be used as initial value for the key in every translation.
 
-> Note. A key will not be extracted when it is an identifier or contains an indentifier (dynamic)
+> Note that it is not necessary to provide the default value of a key every time: it is sufficient and not mandatory to provide it once in the app
 
 #### Naming conventions
 If you use scoped translations, the first property will be used as filename:

 At the end of the build, in root folder a `qwik-speak-inline.log` file is generated which contains:
 - Missing values
-- Translations with dynamic keys
-- Translations with dynamic params
-
-## Qwik Speak Inline Vite plugin & runtime
-When there are translations with dynamic keys or params, you have to use separate files, and add them to `runtimeAssets`:
-
-```typescript
-export const config: SpeakConfig = {
-  /* ... */
-  assets: [
-    'app' // Translations shared by the pages
-  ],
-  runtimeAssets: [
-    'runtime' // Translations with dynamic keys or parameters
-  ]
-};
-```
-Likewise, you can also create scoped runtime files for different pages and pass them to `Speak` components:
-```tsx
-export default component$(() => {
-  return (
-    <Speak assets={['home']} runtimeAssets={['runtimeHome']}>
-      <Page />
-    </Speak>
-  );
-});
-```
-> `runtimeAssets` are serialized and sent to the client, and loaded when required

+# Lazy loading translation
+
+If you are developing a large app, you can consider using lazy loading translation: translations that are lazy loaded only when requested (when the user navigates to a specific section or page of the app):
+
+```mermaid
+C4Container
+  Container_Boundary(a, "App") {
+    Component(a0, "root", "useQwikSpeak", "Translations available in the whole app")
+    Container_Boundary(b1, "Site") {
+      Component(b10, "Page", "useSpeak", "Translations available in Page component")        
+
+    }  
+    Container_Boundary(b2, "Admin") {
+      Component(b20, "layout", "useSpeak", "Translations available in child components")        
+    }
+  }
+```
+
+For lazy loading of files in a specific section, you need to add `useSpeak` to the layout:
+```tsx
+import { useSpeak } from 'qwik-speak';
+
+export default component$(() => {
+  useSpeak({assets:['admin'], runtimeAssets: ['runtimeAdmin']});
+
+  return (
+    <>
+      <main>
+        <Slot />
+      </main>
+    </>
+  );
+});
+```
+or in a specific page:
+```tsx
+export default component$(() => {
+  useSpeak({runtimeAssets: ['runtimePage']});
+
+  return <Page />;
+});
+```
+> Note that you must create a component for the page, because Qwik renders components in isolation, and translations are only available in child components
