-## Méthodes
+## Usage
 
-### `Edge.connect(): Promise`
+Afin de pouvoir utiliser le SDK "client", vous devez inclure dans la page HTML de votre application la balise `<script>` suivante:
 
-> `TODO`
+```html
-
+<script src="/edge/sdk/client.js"></script>
-### `Edge.disconnect(): void`
-
-> `TODO`
-
-
-### `Edge.send(message: Object): void`
-
-> `TODO`
-
-
-### `Edge.rpc(method: string, params: Object): Promise`
-
-> `TODO`
-#### Exemple
-
-**Côté serveur**
-
-```js
-function onInit() {
-    rpc.register(echo);
-}
-
-function echo(ctx, params) {
-    return params;
-}
 ```
 
-**Côté client**
+Vous pourrez ensuite accéder aux variables globales suivantes:
 
-```js
+- [`Edge`](./edge.md) - Client principal d'échange avec le serveur 
-Edge.connect().then(() => {
+- [`EdgeFrame`](./edge-frame.md)
-    Edge.rpc("echo", { hello: "world!" })
-        .then(result => console.log(result))
-        .catch(err => console.error(err));
-});

-### `Edge.upload(blob: Blob, metadata: Object): Promise`
-

-### `Edge.blobUrl(bucketName: string, blobId: string): string`
-
-> `TODO`
-
-## Événements

-### `"message"`
