### Default usage ### Default usage
Execute `mullvad-best-server`. It outputs the code, e.g. `de05`. You can then connect to it with e.g. wireguard using the normal shell scripts. Execute `mullvad-best-server`. It outputs the code, e.g. `de05`. You can then connect to it with e.g. wireguard using the normal shell scripts.
### Extended Output ### Command line parameters
If you want the full server information, execute `mullvad-best-server -o json`. It returns the full json output of the server information.
```angular2html
Usage of dist/mullvad-best-server_darwin_amd64/mullvad-best-server:
-c string
Server country code, e.g. ch for Switzerland (default "ch")
-o string
Output format. 'json' outputs server json
-t string
Server type, e.g. wireguard (default "wireguard")
```
If you want the full server information, execute `mullvad-best-server -o json`. It returns the full json output of the server information.
The `-c` flag allows to give a country code. Else `ch` will be used.
### Specify Country
The -c flag allows to give a country code. Else de/at/ch will be used.
