# Home Assistant website This is the source for the [Home-Assistant.io website](https://home-assistant.io). ## Setup Setting up to contribute to documentation and the process for submitting pull requests is [explained here](https://home-assistant.io/developers/website/). ## Site preview In order to make the preview available on [http://127.0.0.1:4000](http://127.0.0.1:4000), use the command as follows: ```bash $ rake preview ``` ### Setup on Fedora and CentOS On Fedora 22 and later or CentOS 7.1.1503, Ruby is not available by default. Please take the notes here as a little guide for the Ruby installation process. ```bash $ curl -sSL https://rvm.io/mpapis.asc | gpg2 --import - $ curl -L get.rvm.io | bash -s stable $ source ~/.profile $ rvm requirements $ rvm install ruby-2.2.3 $ rvm use ruby-2.2.3 --default $ ruby -v ``` The last command will give you something like this: `ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]`. Then install `bundler`. ```bash $ gem install bundler ``` Now you can follow the [setup instructions](https://home-assistant.io/developers/website/).
