```
* make sure `/var/www/htcount` directory exists
* replace `/path/to/default/template.svg` with your custom template path
* use `ignore-host` to skip local host requests
* to filter today-only records, use `match-time` argument `%d/%b/%Y`
* to filter this month-only records use `%b/%Y`
* make sure the time pattern in the example above corresponds to your `access.log` format
* make sure the log time pattern `%` is escaped to `%%`
### Service management tips
* `systemctl daemon-reload` - update configuration
* `systemctl enable` - launch on system startup
* `systemctl restart htcount` - start systemd service
* `systemctl status htcount` - check if service is running
