+## 👥 Multi-account
+
+Full multi-account currently [is not currently supported](https://github.com/nextcloud/talk-desktop/issues/7).
+
+However, using portable `zip` distribution, you can have several Nextcloud Talk instances run simultaneously. Just rename the executable from default  `Nextcloud Talk` to a custom name. For example: 
+
+```
+/path/to/apps/
+├── home-apps/
+│   └── Nextcloud Talk/
+│       ├── ...
+│       ├── Nextcloud Talk (Home).exe
+│       └── ...
+└── work-apps/
+    └── Nextcloud Talk/
+        ├── ...
+        ├── Nextcloud Talk (Work).exe
+        └── ...
+```
