After deployment, you can directly test and verify the installation using the `hx` command in the terminal.
> If you encounter any errors during deployment, you can try adding the `--show-trace -L` parameters to the `nixos-rebuild` command to get detailed error information.
Additionally, if you just want to try out the latest version of Helix and decide whether to install it on your system later, there is a simpler way to do it in one command (but as mentioned earlier, compiling from source will take a long time):
