+Summary:
+
+The purpose of the VPP configuration utility is to allow the user to configure
+VPP in a simple and safe manner. The utility takes input from the user and
+then modifies the key configuration files. The user can then examine these files
+to be sure they are correct and then actually apply the configuration. The user
+can also install a released and stable version of VPP. This is currently
+released with release 17.07.
+
+Use:
+
+The installation and executing of the VPP configuration utility is simple. First
+install the python pip module. Using pip install, then pip install vpp-config.
+Then simply type Òvpp-configÓ and answer the questions. If you are not sure what
+to answer choose the default. For yes or no questions the capital letter
+designates the default. For example, for a question that shows [Y/n] Y is the
+default. For numbers the default is within the brackets for example for a
+question that shows [1024]. 1024 is the default.
+
+The flow of the utility is to inspect the system, if VPP is not install it,
+create dry run configurations, inspect the files created during the dry run,
+apply the configuration and then inspect the system again and then repeat.
+
+Caveats:
+
+- Only supports Ubuntu, centos7 is coming shortly.
+- When Inspecting the system, you may see a Huge page error, inspect the system a
+few more times, if the error persists it is real.
+
+For Developers:
+
+Modifying the code is reasonable simple. The process would be edit and debug the
+code from the root directory. In order to do this, we need a script that will copy
+or data files to the proper place. This is where they end up with pip install. For
+Ubuntu, this is /usr/local/vpp/vpp-config. I have provided a script that will copy
+the relevant files correctly. I have also provided a script that will clean the
+environment so you can start from scratch. These are the steps to run the utility
+in this environment. The scripts are meant to be run from the root directory.
+
+ ./scripts/clean.sh
+ ./scripts/cp-data.sh
+ ./vpp_config.py
+
+When the utility is installed with pip the wrapper scripts/vpp-config is written to
+/usr/local/bin. However, the starting point when debugging this script locally is
+./vpp_config.py. Run the utility by executing ./vpp_config.py from the root directory.
+
+The start point in the code is in vpp_config.py. However, most of the work is done in
+the files in ./vpplib
+
+Uploading to PyPi:
+
+To upload this utility to PpPi simple do the following. Currently, I have my own account
+when we want everyone to contribute we will need to change that.
+
+ sudo ÐH bash
+ cd vpp_config
+ python setup.py sdist bdist_wheel
+ twine upload dist/*
+
+Example Run:
+
+# pip install vpp-config
+# vpp-config
+
+Welcome to the VPP system configuration utility
+
+These are the files we will modify:
+ /etc/vpp/startup.conf
+ /etc/sysctl.d/80-vpp.conf
+ /etc/default/grub
+
+Before we change them, we'll create working copies in /usr/local/vpp/vpp-config/dryrun
+Please inspect them carefully before applying the actual configuration (option 3)!
