* Updating development environment setup guide
Added more complete instructions for setting up a development environment for Home Assistant. Including details of dependencies, setting up venv. This is based on notes captured from setting up a dedicated hass dev environment on Debian 8.6.0
* Update development_environment.markdown
Updated as a result of feedback on pull request: https://github.com/home-assistant/home-assistant.github.io/pull/1804
Adding reminder to activate virtual environment before running setup along with adding reference to indicate apt-get may not be applicable to distro in use.
* Revert change to instruction to run hass
Remove statement about running hass with --open-ui and what it does (wrongly stated). Based on feedback from @balloob.
* Updated setting up venv as pyvenv is being deprecated
As of Python 3.6 pyvenv has been deprecated in favour of python3 -m venv.
Further changes may be required following resolution of discussion around setting up venv in a sub directory vs at the top level of the project.
* Remove details of Frontend requirements for NVM and Node
Given change [#5507](https://github.com/home-assistant/home-assistant/pull/5507) only attempts to setup the frontend if nvm is present. It makes sense to remove the details from here, since that was mainly around avoiding errors in the first time setup scenario. Instead I've adjusted the text to point to the FrontEnd Dev section.
* Updated centos instructions
yum install commands needs to be split so that EPEL repo is added first ahead of attempting to install other dependencies.
* Create configuration_yaml_by_shortbloke.markdown
