+### Using container options
+
+You can specialize the options used to start containers using the `options` definitions:
+
+```yaml
+servers:
+  web:
+    - 192.168.0.1
+    - 192.168.0.2
+  job:
+    hosts:
+      - 192.168.0.3
+      - 192.168.0.4
+    cmd: bin/jobs
+    options:
+      cap-add: true
+      cpu-count: 4
+```
+
+That'll start the job containers with `docker run ... --cap-add --cpu-count 4 ...`.

 ### Using remote builder for native multi-arch
 
 If you're developing on ARM64 (like Apple Silicon), but you want to deploy on AMD64 (x86 64-bit), you can use multi-architecture images. By default, MRSK will setup a local buildx configuration that does this through QEMU emulation. But this can be quite slow, especially on the first build.
