# User Documentation [toc] ## Initial Administrator After system initialization, the database will initialize a fixed administrator user (username: admin; password: kerbal_admin). Please hand over this user to the designated personnel for management, and make sure to change the password. ## Account Registration Those who wish to use the container can apply to the administrator. The administrator has the authority to specify whether the user being created will be an administrator or not. After the user is created, they need to confirm the user creation by email to complete the process. ## CPU Resource Allocation - Click `Create` button <img src="https://raw.githubusercontent.com/zephyrszwc/zephyrs-image/master/202305312044877.png" alt="image-20230531204434718" style="zoom:30%;" /> - Switch to CPU tab, and choose your domain configuration according to your requirement <img src="https://raw.githubusercontent.com/zephyrszwc/zephyrs-image/master/202305312045664.png" alt="image-20230531204535565" style="zoom:30%;" /> ## GPU Resource Allocation - Click `Create` button <img src="https://raw.githubusercontent.com/zephyrszwc/zephyrs-image/master/202305312044877.png" alt="image-20230531204434718" style="zoom:30%;" /> - Switch to CPU tab, and choose your domain configuration according to your requirement <img src="https://raw.githubusercontent.com/zephyrszwc/zephyrs-image/master/202305312047185.png" alt="image-20230531204749077" style="zoom:30%;" /> ## Make your own snapshot We offer the functionality of custom image provisioning, allowing you to configure the environment and libraries for existing user domains.
