+# Deployment guide for Docker Swarm
+
+> Note: The best place to start is the README file in the faas or faas-netes repo.
+
+## Initialize Swarm Mode
+
+Use either a single host or multi-node setup.
+
+This is how you initialize your master node:
+
+```
+# docker swarm init
+```
+
+If you have more than one IP address you may need to pass a string like `--advertise-addr eth0` to this command.
+
+Then copy any join token commands you see and run them on your worker nodes.
+
+## Deploy the stack
+
+```
+$ git clone https://github.com/alexellis/faas && \
+  cd faas && \
+  git checkout 0.6.0 && \
+  ./deploy_stack.sh
+```
+
+## Test the UI
+
+Within a few seconds (or minutes if on a poor WiFi connection) the API gateway and sample functions will be pulled into your local Docker library and you will be able to access the UI at:
+
+http://localhost:8080
