+## Retrieving SSH Authorized Keys
+
+### From a GitHub User
+
+Using the `coreos-ssh-import-github` field, we can import public SSH keys from a GitHub user to use as authorized keys to a server.
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-github: elroy
+```
+
+### From an HTTP Endpoint
+
+We can also pull public SSH keys from any HTTP endpoint which matches [GitHub's API response format](https://developer.github.com/v3/users/keys/#list-public-keys-for-a-user).
+For example, if you have an installation of GitHub Enterprise, you can provide a complete URL with an authentication token:
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://github-enterprise.example.com/api/v3/users/elroy/keys?access_token=<TOKEN>
+```
+
+You can also specify any URL whose response matches the JSON format for public keys:
+
+```yaml
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://example.com/public-keys

It should also contain a `openstack/latest/user_data` relative path. Usually used in installations which are configured by USB Flash sticks or CDROM media.|
+|Kernel command line: `cloud-config-url=http://example.com/user_data`.| You can find this string using this command `cat /proc/cmdline`. Usually used in [PXE](/os/docs/latest/booting-with-pxe.html) or [iPXE](/os/docs/latest/booting-with-ipxe.html) boots.|
+|`/var/lib/coreos-install/user_data`| When you install CoreOS manually using the [coreos-install](/os/docs/latest/installing-to-disk.html) tool. Usually used in bare metal installations.|
+|`/usr/share/oem/cloud-config.yml`| Path for OEM images.|
+|`/var/lib/coreos-vagrant/vagrantfile-user-data`| Vagrant OEM scripts automatically store Cloud-Config into this path. |
+|`/var/lib/waagent/CustomData`| Azure platform uses OEM path for first Cloud-Config initialization and then `/var/lib/waagent/CustomData` to apply your settings.|
+|`http://169.254.169.254/metadata/v1/user-data` `http://169.254.169.254/2009-04-04/user-data` `https://metadata.packet.net/userdata`|DigitalOcean, EC2 and Packet cloud providers correspondingly use these URLs to download Cloud-Config.|

+## Cloud-Config VMWare Guestinfo Variables
+
+coreos-cloudinit accepts configuration from the VMware RPC API's *guestinfo*
+facility. This datasource can be enabled with the `--from-vmware-guestinfo`
+flag to coreos-cloudinit.
+
+The following guestinfo variables are recognized and processed by cloudinit
+when passed from the hypervisor to the virtual machine at boot time. Note that
+property names are prefixed with `guestinfo.` in the VMX, e.g., `guestinfo.hostname`.
+
+|            guestinfo variable             |              type               |
+|:--------------------------------------|:--------------------------------|
+| `hostname`                            | `hostname`                      |
+| `interface.<n>.name`                  | `string`                        |
+| `interface.<n>.mac`                   | `MAC address`                   |
+| `interface.<n>.dhcp`                  | `{"yes", "no"}`                 |
+| `interface.<n>.role`                  | `{"public", "private"}`         |
+| `interface.<n>.ip.<m>.address`        | `CIDR IP address`               |
+| `interface.<n>.route.<l>.gateway`     | `IP address`                    |
+| `interface.<n>.route.<l>.destination` | `CIDR IP address`               |
+| `dns.server.<x>`                      | `IP address`                    |
+| `coreos.config.data`                  | `string`                        |
+| `coreos.config.data.encoding`         | `{"", "base64", "gzip+base64"}` |
+| `coreos.config.url`                   | `URL`                           |
+
+Note: "n", "m", "l", and "x" are 0-indexed, incrementing integers. The
+identifier for an `interface` does not correspond to anything outside of this
+configuration; it serves only to distinguish between multiple `interface`s.
+
+The guide to [booting on VMWare][bootvmware] is the starting point for more
+information about configuring and running CoreOS on VMWare.

-=====
-
-Cepko implements easy-to-use communication with CloudSigma's VMs through a
-virtual serial port without bothering with formatting the messages properly nor
-parsing the output with the specific and sometimes confusing shell tools for
-that purpose.
-
-Having the server definition accessible by the VM can be useful in various
-ways. For example it is possible to easily determine from within the VM, which
-network interfaces are connected to public and which to private network.
-Another use is to pass some data to initial VM setup scripts, like setting the
-hostname to the VM name or passing ssh public keys through server meta.
-
-Example usage:
-
-    package main
-
-    import (
-            "fmt"
-
-            "github.com/cloudsigma/cepgo"
-    )
-
-    func main() {
-            c := cepgo.NewCepgo()
-            result, err := c.Meta()
-            if err != nil {

-            }

-// The properties array of StartTransientUnit() may take many of the settings
-// that may also be configured in unit files. Not all parameters are currently
-// accepted though, but we plan to cover more properties with future release.
-// Currently you may set the Description, Slice and all dependency types of
-// units, as well as RemainAfterExit, ExecStart for service units,
-// TimeoutStopUSec and PIDs for scope units, and CPUAccounting, CPUShares,
-// BlockIOAccounting, BlockIOWeight, BlockIOReadBandwidth,
-// BlockIOWriteBandwidth, BlockIODeviceWeight, MemoryAccounting, MemoryLimit,
-// DevicePolicy, DeviceAllow for services/scopes/slices. These fields map
-// directly to their counterparts in unit files and as normal D-Bus object
-// properties. The exception here is the PIDs field of scope units which is
-// used for construction of the scope only and specifies the initial PIDs to
-// add to the scope object.

-go.dbus
--------
-
-go.dbus is a simple library that implements native Go client bindings for the
-D-Bus message bus system.
-
-### Features
-
-* Complete native implementation of the D-Bus message protocol
-* Go-like API (channels for signals / asynchronous method calls, Goroutine-safe connections)
-* Subpackages that help with the introspection / property interfaces
-
-### Installation
-
-This packages requires Go 1.1. If you installed it and set up your GOPATH, just run:
-
-```
-go get github.com/guelfey/go.dbus
-```
-
-If you want to use the subpackages, you can install them the same way.
-
-### Usage
-
-The complete package documentation and some simple examples are available at
-[godoc.org](http://godoc.org/github.com/guelfey/go.dbus). Also, the
-[_examples](https://github.com/guelfey/go.dbus/tree/master/_examples) directory
-gives a short overview over the basic usage. 
-
-Please note that the API is considered unstable for now and may change without
-further notice.
-
-### License
-
-go.dbus is available under the Simplified BSD License; see LICENSE for the full
-text.

-Package dbus implements bindings to the D-Bus message bus system.
-
-To use the message bus API, you first need to connect to a bus (usually the
-session or system bus). The acquired connection then can be used to call methods
-on remote objects and emit or receive signals. Using the Export method, you can
-arrange D-Bus methods calls to be directly translated to method calls on a Go
-value.
-
-Conversion Rules
-
-For outgoing messages, Go types are automatically converted to the
-corresponding D-Bus types. The following types are directly encoded as their
-respective D-Bus equivalents:
-
-     Go type     | D-Bus type
-     ------------+-----------
-     byte        | BYTE
-     bool        | BOOLEAN
-     int16       | INT16
-     uint16      | UINT16
-     int32       | INT32
-     uint32      | UINT32
-     int64       | INT64
-     uint64      | UINT64
-     float64     | DOUBLE
-     string      | STRING
-     ObjectPath  | OBJECT_PATH
-     Signature   | SIGNATURE
-     Variant     | VARIANT
-     UnixFDIndex | UNIX_FD
-
-Slices and arrays encode as ARRAYs of their element type.
-
-Maps encode as DICTs, provided that their key type can be used as a key for
-a DICT.
-
-Structs other than Variant and Signature encode as a STRUCT containing their
-exported fields. Fields whose tags contain `dbus:"-"` and unexported fields will
-be skipped.
-
-Pointers encode as the value they're pointed to.
-
-Trying to encode any other type or a slice, map or struct containing an
-unsupported type will result in an InvalidTypeError.
-
-For incoming messages, the inverse of these rules are used, with the exception
-of STRUCTs. Incoming STRUCTS are represented as a slice of empty interfaces
-containing the struct fields in the correct order. The Store function can be
-used to convert such values to Go structs.
-
-Unix FD passing
-
-Handling Unix file descriptors deserves special mention. To use them, you should
-first check that they are supported on a connection by calling SupportsUnixFDs.
-If it returns true, all method of Connection will translate messages containing
-UnixFD's to messages that are accompanied by the given file descriptors with the
-UnixFD values being substituted by the correct indices. Similarily, the indices
-of incoming messages are automatically resolved. It shouldn't be necessary to use
-UnixFDIndex.

-GoSerial
-========
-A simple go package to allow you to read and write from the
-serial port as a stream of bytes.
-
-Details
--------
-It aims to have the same API on all platforms, including windows.  As
-an added bonus, the windows package does not use cgo, so you can cross
-compile for windows from another platform.  Unfortunately goinstall
-does not currently let you cross compile so you will have to do it
-manually:
-
-    GOOS=windows make clean install
-
-Currently there is very little in the way of configurability.  You can
-set the baud rate.  Then you can Read(), Write(), or Close() the
-connection.  Read() will block until at least one byte is returned.
-Write is the same.  There is currently no exposed way to set the
-timeouts, though patches are welcome.
-
-Currently all ports are opened with 8 data bits, 1 stop bit, no
-parity, no hardware flow control, and no software flow control.  This
-works fine for many real devices and many faux serial devices
-including usb-to-serial converters and bluetooth serial ports.
-
-You may Read() and Write() simulantiously on the same connection (from
-different goroutines).
-
-Usage
------
-```go
-package main
-
-import (
-        "github.com/tarm/goserial"
-        "log"
-)
-
-func main() {
-        c := &serial.Config{Name: "COM45", Baud: 115200}
-        s, err := serial.OpenPort(c)
-        if err != nil {
-                log.Fatal(err)
-        }
-        
-        n, err := s.Write([]byte("test"))
-        if err != nil {
-                log.Fatal(err)
-        }
-        
-        buf := make([]byte, 128)
-        n, err = s.Read(buf)
-        if err != nil {
-                log.Fatal(err)
-        }
-        log.Print("%q", buf[:n])
-}
-```
-
-Possible Future Work
--------------------- 
-- better tests (loopback etc)
