+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this

+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,

+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# CentOS Cloud-Init Datasource for VMware VMX Guestinfo
+This project uses Docker to build an RPM for CentOS that provides a
+cloud-init datasource for VMware's VMX Guestinfo interface.
+
+## Getting Started
+Docker is required to build the RPM. Once Docker is installed simply run:
+
+```shell
+$ make
+```
+
+The RPM is created at `rpmbuild/RPMS/noarch/cloud-init-vmx-guestinfo-VERSION-RELEASE.noarch.rpm`.
+
+## Installation
+Either the `rpm` or `yum` tools can be used to install the RPM on CentOS.
+
+```shell
+$ yum install https://s3-us-west-2.amazonaws.com/cnx.vmware/cicd/centos/cloud-init-vmx-guestinfo-1.0.4-0.noarch.rpm
+```
+
+The above command will also install the required `cloud-init` dependency.
+
+## Creating a cloud-config file
+The first step to use the data source is to create a cloud config file:
+
+```yaml
+#cloud-config
+
+users:
+  - default
+  - name: akutz
+    primary_group: akutz
+    sudo: ALL=(ALL) NOPASSWD:ALL
+    groups: sudo, wheel
+    ssh_import_id: None
+    lock_passwd: true
+    ssh_authorized_keys:
+      - ssh-rsa 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 sakutz@gmail.com
+```
+
+## Assigning the cloud-config data to the VM's Guestinfo
+Please note that this step requires that the VM be powered off.
+
+Once the cloud config file has been created, use the 
+[`govc`](https://github.com/vmware/govmomi/blob/master/govc/USAGE.md#vmchange)
+tool's `vm.change` command to set the appropriate keys on the powered-off VM:
+
+```shell
+$ govc vm.change -vm $VM -e guestinfo.userdata=$(cat cloud-config.yaml | gzip -9 | base64)
+$ govc vm.change -vm $VM -e guestinfo.userdata.encoding=gzip+base64
+```
+
+## Using the cloud-init VMX Guestinfo datasource
+Power the VM back on. If all went according to plan, the CentOS box has been
+locked down to SSH access only for the user defined in the above cloud-config
+YAML file.
+
+## Conclusion
+To learn more about how to use cloud-init with CentOS, please see the cloud-init
+[documentation](https://cloudinit.readthedocs.io/en/latest/index.html) for more 
+examples and reference information for the cloud-config files.
