+# Example REST API Client
+
+This is an implementation of a cAdvisor REST API in Go.  You can use it like this:
+
+```go
+client, err := client.NewClient("http://192.168.59.103:8080/")
+```
+
+Obviously, replace the URL with the path to your actual cAdvisor REST endpoint.
+
+
+### MachineInfo
+
+```go
+client.MachineInfo()
+```
+
+There is no v2 MachineInfo API, so the v2 client exposes the [v1 MachineInfo](../../info/v1/machine.go#L131)
+
+```
+(*v1.MachineInfo)(0xc208022b10)({
+ NumCores: (int) 4,
+ MemoryCapacity: (int64) 2106028032,
+ Filesystems: ([]v1.FsInfo) (len=1 cap=4) {
+  (v1.FsInfo) {
+   Device: (string) (len=9) "/dev/sda1",
+   Capacity: (uint64) 19507089408
+  }
+ }
+})
+```
+
+You can see the full specification of the [MachineInfo struct in the source](../../info/v1/machine.go#L131)
+
+### VersionInfo
+
+```go
+client.VersionInfo()
+```
+
+This method returns the cAdvisor version.
+
+### Attributes
+
+```go
+client.Attributes()
+```
+
+This method returns a [cadvisor/info/v2/Attributes](../../info/v2/machine.go#L24) struct with all the fields filled in. Attributes includes hardware attributes (as returned by MachineInfo) as well as software attributes (eg. software versions). Here is an example return value:
+
+```
+(*v2.Attributes)({
+ KernelVersion: (string) (len=17) "3.13.0-44-generic"
+ ContainerOsVersion: (string) (len=18) "Ubuntu 14.04.1 LTS"
+ DockerVersion: (string) (len=9) "1.5.0-rc4"
+ CadvisorVersion: (string) (len=6) "0.10.1"
+ NumCores: (int) 4,
+ MemoryCapacity: (int64) 2106028032,
+ Filesystems: ([]v2.FsInfo) (len=1 cap=4) {
+  (v2.FsInfo) {
+   Device: (string) (len=9) "/dev/sda1",
+   Capacity: (uint64) 19507089408
+  }
+ }
+})
+```
+
+You can see the full specification of the [Attributes struct in the source](../../info/v2/machine.go#L24)
