 ```typescript
 const genesiscloud = new GenesisCloudClient({
-  TOKEN: "your_api_token_here",
+  TOKEN: process.env.GENESISCLOUD_TOKEN,
 });
 ```
 
 ## Examples
 
+### Error handling
+
+Error handling can be done using the try/catch with the async/await syntax. For example:
+
+```typescript
+const listImages = async () => {
+  try {
+    const { images } = await genesiscloud.images.listImages({});
+    return images;
+  } catch (error) {
+    // ... handle the error
+  }
+};
+```

 ### Managing Instances
 
 Listing Instances:
 
 ```typescript
-const instances = await genesiscloud.instances.listInstances({
+const { instances } = await genesiscloud.instances.listInstances({
   page: 1,
   perPage: 100,
 });
