title: Hello World

Minimal systemg service.
```yaml
version: "1"
services:
counter:
command: "sh counter.sh"
```
```bash
$ i=1
$ while true; do
$ echo "Count: $i"
$ i=$((i + 1))
$ sleep 1
$ done
```
```bash
$ sysg start
$ sysg logs --service counter
$ sysg stop
```
You'll see:
```
Count: 1
Count: 2
Count: 3
```
## Next steps
Add a restart policy to handle crashes:
```yaml
version: "1"
services:
counter:
command: "sh counter.sh"
restart_policy: "always"
```
