 ### A foreword on security
 
 These instructions are for a development environment. If you plan to expose OpenFaaS on the public Internet you need to enable basic authentication with a proxy such as Kong or Traefik at a minimum. TLS is also highly recommended and freely available with LetsEncrypt.org. [Kong guide](https://github.com/openfaas/faas/blob/master/guide/kong_integration.md) [Traefik guide](https://github.com/openfaas/faas/blob/master/guide/traefik_integration.md).

+## 1.1 Join any workers you need
 
 Log into your worker node and type in the output from `docker swarm init` on the master. If you've lost this info then type in `docker swarm join-token worker` and then enter that on the worker.
 
 It's also important to pass the `--advertise-addr` string to any hosts which have a public IP address.
 
 > Note: check whether you need to enable firewall rules for the [Docker Swarm ports listed here](https://docs.docker.com/engine/swarm/swarm-tutorial/).

 Clone OpenFaaS and then checkout the latest stable release:
 
 ```
 $ git clone https://github.com/openfaas/faas && \
   cd faas && \
-  git checkout 0.7.1 && \
+  git checkout 0.7.7 && \
   ./deploy_stack.sh
 ```
 
 `./deploy_stack.sh` can be run at any time and includes a set of sample functions. You can read more about these in the [TestDrive document](https://github.com/openfaas/faas/blob/master/TestDrive.md)
 
-## Test out the UI

+## 2.1 Test out 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
+http://127.0.0.1:8080
 
-If you're running on Linux you may find that `localhost` times out. In this case force an IPv4 address such as http://127.0.0.1:8080.
