Note that the two link files may need to be reconstructed. ## Project Management - Create Project Log in as root. Enter the project description and its SSID. The SSID will become the Wi-Fi name. - Add WTP Log in as root. In the menu, choose `Devices->WTPs` then Add WTP. Enter the WTP's MAC address and its description. - Add STA Log in as user. Choose the project just created by clicking the green flag mark. In the menu, choose `$PROJECT_NAME` then Add Station. Enter the STA's MAC address and its description. Then the STA should be able to connect the network. - STA handover Log in as user. In the menu, choose `Clients->LVAPs`. Here we can manage which STA connect to which WTP. We can also handover STA to other WTP under the same project. ## Reference [How to Install Docker On Ubuntu 18.04](https://phoenixnap.com/kb/how-to-install-docker-on-ubuntu-18-04)
