+## Running Fission on your Cluster
+
+### Setup Kubernetes
+
+You can install Kubernetes on your laptop with [minikube](https://github.com/kubernetes/minikube):
+
+#### Install and start Kubernetes on OSX:
+```bash
+  $ curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin
+  $ curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.14.0/minikube-darwin-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
+  $ minikube start
+```
+
+#### Or, install and start Kubernetes on Linux:
+```bash
+  $ curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin
+  $ curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.14.0/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
+  $ minikube start
+```
+
+Or, you can use [Google Container Engine's](https://cloud.google.com/container-engine/) free trial to get a 3 node cluster.
+
+### Verify access to the cluster
+
+```
+  $ kubectl version
+```
+
+### Get and Run Fission: Minikube or Local cluster
+
+If you're using minikube or no cloud provider, use these commands to
+set up services with NodePort.  This exposes fission on ports 31313
+and 31314.
+
+```
+  $ kubectl create -f http://fission.io/fission.yaml
+  $ kubectl create -f http://fission.io/fission-nodeport.yaml
+```
+
+Set the FISSION_URL and FISSION_ROUTER environment variables.
+FISSION_URL is used by the fission CLI to find the server.
+FISSION_URL should be prefixed with a `http://`.  (FISSION_ROUTER is
+only needed for the examples below to work.)
+
+If you're using minikube, use these commands:
+
+```
+  $ export FISSION_URL=http://$(minikube ip):31313
+  $ export FISSION_ROUTER=$(minikube ip):31314
+```
+
+
+### Get and Run Fission: GKE or other Cloud
+
+If you're using GKE or any other cloud provider that supports the
+LoadBalancer service type, use these commands:
+
+```
+  $ kubectl create -f http://fission.io/fission.yaml
+  $ kubectl create -f http://fission.io/fission-cloud.yaml
+```
+
+Save the external IP addresses of controller and router services in
+FISSION_URL and FISSION_ROUTER, respectively.  Wait for services to
+get IP addresses (check this with ```kubectl --namespace fission get
+svc```).  Then:
+
+```
+  $ export FISSION_URL=http://$(kubectl --namespace fission get svc controller -o=jsonpath='{..ip}')
+  $ export FISSION_ROUTER=$(kubectl --namespace fission get svc router -o=jsonpath='{..ip}')
+```
+
+### Install the client CLI
+
+Get the CLI binary for Mac:
+
+```
+  $ curl http://fission.io/mac/fission > fission && chmod +x fission && sudo mv fission /usr/local/bin/
+```
+
+Or Linux:
+
+```
+  $ curl http://fission.io/linux/fission > fission && chmod +x fission && sudo mv fission /usr/local/bin/
+```
+
+### Run an example
+
+Finally, you're ready to use Fission!
+
+```
+  $ fission env create --name nodejs --image fission/node-env
+
+  $ echo 'module.exports = function(context, callback) { callback(200, "Hello, world!\n"); }' > hello.js  
+
+  $ fission function create --name hello --env nodejs --code hello.js
+  
+  $ fission route create --method GET --url /hello --function hello
+  
+  $ curl http://$FISSION_ROUTER/hello
+  Hello, world!
+```
