 ## Usage
 
 NMS needs to be configured with the following environment variables:
+- `SWAGGER_HOST`: The host of the webui. This is used to redirect the swagger operations to the webui.
 - `UPF_CONFIG_PATH`: The path to the UPF configuration file. An example of this file can be seen in the `examples/` directory.
 - `GNB_CONFIG_PATH`: The path to the gNodeB configuration file. An example of this file can be seen in the `examples/` directory.
 
 ```console
+export SWAGGER_HOST=10.1.182.28
 export UPF_CONFIG_PATH=/path/to/upf_config.json
 export GNB_CONFIG_PATH=/path/to/gnb_config.json
