+## Running From Source
+
+You will need to setup a virtualenv to run from source and execute the unit tests.
+
+$ virtualenv oo-install
+$ source ./oo-install/bin/activate
+$ virtualenv --relocatable ./oo-install/
+$ python setup.py install
+
+The virtualenv bin directory should now be at the start of your $PATH, and oo-install is ready to use from your shell.
+
+You can exit the virtualenv with:
+
+$ deactivate
+
+## Testing
+
+Install some testing libraries: (we cannot do this via setuptools due to the version virtualenv bundles)
+
+$ pip install mock nose
+
+Then run the tests with:
+
+$ oo-install/bin/nosetests

+# oo-install Supported Configuration File
+
+Upon completion oo-install will write out a configuration file representing the settings that were gathered and used. This configuration file, or one crafted by hand, can be used to run or re-run the installer and add additional hosts, upgrade, or re-install.
+
+The default location this config file will be written to ~/.config/openshift/installer.cfg.yml.
+
+## Example
+
+```
+variant: openshift-enterprise
+variant_version: 3.0
+ansible_ssh_user: root
+hosts:
+- ip: 10.0.0.1
+  hostname: master-private.example.com
+  public_ip: 24.222.0.1
+  public_hostname: master.example.com
+  master: true
+  node: true
+  containerized: true
+- ip: 10.0.0.2
+  hostname: node1-private.example.com
+  public_ip: 24.222.0.2
+  public_hostname: node1.example.com
+  node: true
+- ip: 10.0.0.3
+  hostname: node2-private.example.com
+  public_ip: 24.222.0.3
+  public_hostname: node2.example.com
+  node: true
+```
+
+## Primary Settings
+
+### variant
+
+The OpenShift variant to install. Currently valid options are:
+
+ * openshift-enterprise
+ * atomic-enterprise
+
+### variant_version (optional)
+
+Default: Latest version for your chosen variant.
+
+A version which must be valid for your selected variant. If not specified the latest will be assumed.
+
+Examples: 3.0, 3.1, etc.
+
+### hosts
+
+This section defines a list of the hosts you wish to install the OpenShift master/node service on.
+
+*ip* or *hostname* must be specified so the installer can connect to the system to gather facts before proceeding with the install.
+
+If *public_ip* or *public_hostname* are not specified, this information will be gathered from the facts and the user will be asked to confirm in an editor. For an unattended install, the installer will error out. (you must provide complete host records for an unattended install)
+
+*master* and *node* determine the type of services that will be installed. One of these must be set to true for the configuration file to be considered valid.
+
+*containerized* indicates you want to run OpenShift services in a container on this host.
+
+### ansible_ssh_user
+
+Default: root
+
+Defines the user ansible will use to ssh to remote systems for gathering facts and the installation.
+
+### ansible_log_path
+
+Default: /tmp/ansible.log
+
+

+= oo-install Portable Installer Package
+
+This package is identical to the installer package that can be downloaded
+and executed directly from https://install.openshift.com/.
+
+NOTE: It will still be necessary for this installer to download RPMs from the
+internet, unless you have already set up the necessary local repositories.
+
+To run the installer from this package, run the following command:
+
+$ ./LAUNCHERNAME
+
+That command script and the packaged zip file can be burned to a CD or
+written to a USB drive and used to run the oo-install utility in places
+where the web-based installer is not reachable.
+
+All of the command-line arguments supported by oo-install can be passed
+to this launcher application.
+
+For more information for Enterprise installs, refer to the OpenShift
+Enterprise Administrator Guide:
+https://docs.openshift.com/enterprise/latest/welcome/index.html

+A sample Python project
+=======================
+
+This is the description file for the project.
+
+The file should use UTF-8 encoding and be written using ReStructured Text. It
+will be used to generate the project webpage on PyPI, and should be written for
+that purpose.
+
+Typical contents for this file would include an overview of the project, basic
+usage examples, etc. Generally, including the project changelog in here is not
+a good idea, although a simple "What's New" section for the most recent version
+may be appropriate.
