+Note: building `wakunode2` requires 2GB of RAM. The build will fail on systems not fulfilling this requirement.
+
+Setting up a `wakunode2` on the smallest [digital ocean](https://docs.digitalocean.com/products/droplets/how-to/) droplet, you can either

+* activate swap on the smallest droplet, or
+* use Docker.
