+# Third Party Resources Example
+
+This particular example demonstrates how to perform basic operations such as:
+
+* How to register a new ThirdPartyResource (custom Resource type)
+* How to create/get/list instances of your new Resource type (update/delete/etc work as well but are not demonstrated) 
+* How to setup a controller on Resource handling create/update/delete events
+
+## Running
+
+```
+# assumes you have a working kubeconfig, not required if operating in-cluster
+go run *.go -kubeconfig=$HOME/.kube/config
+```
+
+## Use Cases
+
+ThirdPartyResources can be used to implement custom Resource types for your Kubernetes cluster.
+These act like most other Resources in Kubernetes, and may be `kubectl apply`'d, etc.
+
+Some example use cases:
+
+* Provisioning/Management of external datastores/databases (eg. CloudSQL/RDS instances)
+* Higher level abstractions around Kubernetes primitives (eg. a single Resource to define an etcd cluster, backed by a Service and a ReplicationController) 
+
+## Defining types
+
+Each instance of your ThirdPartyResource has an attached Spec, which should be defined via a `struct{}` to provide data format validation.
+In practice, this Spec is arbitrary key-value data that specifies the configuration/behavior of your Resource.
+
+For example, if you were implementing a ThirdPartyResource for a Database, you might provide a DatabaseSpec like the following:
+
+``` go
+type DatabaseSpec struct {
+	Databases []string `json:"databases"`
+	Users     []User   `json:"users"`
+	Version   string   `json:"version"`
+}
+
+type User struct {
+	Name     string `json:"name"`
+	Password string `json:"password"`
+}
+```

+# Workqueue Example
+
+This example demonstrates how to write a controller which follows the states
+of watched resources.
+
+It demonstrates how to:
+ * combine the workqueue with a cache to a full controller
+ * synchronize the controller on startup
+
+The example is based on https://github.com/kubernetes/community/blob/master/contributors/devel/controllers.md.
+
+## Running
+
+```
+# if outside of the cluster
+go run *.go -kubeconfig=/my/config -logtostderr=true
+```
