First-time setup
Import first, then enable the proxy
The client reads and manages configurations; it doesn't replace a remote service. Once you have a subscription URL you're authorized to use, add it to a subscription group and update it. For a single share link, use the appropriate import option. Pasting a webpage URL, account page, or block of explanatory text usually won't produce a valid configuration.
After selecting a configuration, set the system proxy on desktop or start the VPN connection on Android. Test with the apps you actually need and check the client's error logs. An enabled toggle alone doesn't mean the connection is working.

Already have the client
Back up before updating
Before updating, note your current configuration sources, local listening ports, DNS, and custom routes. Use the client's export or backup feature, and store any credentials securely. Don't upload backups publicly or post them as screenshots in discussion forums.
Quit the old client before updating. When moving between interfaces, cores, or major versions, use the import method supported by the new release instead of overwriting all files. Test your frequently used apps after updating, then decide whether to enable advanced features such as TUN.
