######2 - Nodes setup
The only requirement for Swarm nodes is to run a regular Docker daemon.
The only requirement for Swarm nodes is to run a regular Docker daemon (version `1.4.0` and later).
In order for Swarm to be able to communicate with its nodes, they must bind on a network interface.
This can be achieved by starting Docker with the `-H` flag (e.g. `-H 0.0.0.0:2375`).
Currently, nodes must be running the Docker **master** version.
Master binaries are available here: https://master.dockerproject.com/
### Example usage
```bash
