# React Documentation & Website

We use [Jekyll](http://jekyllrb.com/) to build the site using ([mostly](http://zpao.com/posts/adding-line-highlights-to-markdown-code-fences/)) Markdown, and we host it by pushing HTML to [GitHub Pages](http://pages.github.com/).

## Installation

If you are working on the site, you will want to install and run a local copy of it.

### Dependencies

In order to use Jekyll, you will need to have Ruby installed.

 - [Ruby](http://www.ruby-lang.org/) (version >= 1.8.7)
 - [RubyGems](http://rubygems.org/) (version >= 1.3.7)
 - [Bundler](http://gembundler.com/)

Mac OS X comes pre-installed with Ruby, but you may need to update RubyGems (via `gem update --system`).
Otherwise, [RVM](https://rvm.io/) and [rbenv](https://github.com/sstephenson/rbenv) are popular ways to install Ruby.
Once you have RubyGems and installed Bundler (via `gem install bundler`), use it to install the dependencies:

```sh
$ cd react/docs
$ bundle install # Might need sudo.
$ npm install # Might need sudo.
```

### Instructions

The site requires React, so first make sure you've built the project (via `grunt`).

Use Jekyll to serve the website locally (by default, at `http://localhost:4000`):

```sh
$ cd react/docs
$ rake
$ jekyll serve -w
$ open http://localhost:4000/react/
```

We use [SASS](http://sass-lang.com/) (with [Bourbon](http://bourbon.io/)) for our CSS, and we use JSX to transform some of our JS.
If you only want to modify the HTML or Markdown, you do not have to do anything because we package pre-compiled copies of the CSS and JS.
If you want to modify the CSS or JS, use [Rake](http://rake.rubyforge.org/) to compile them:

```sh
$ cd react/docs
$ rake watch # Automatically compiles as needed.
# rake         Manually compile CSS and JS.
# rake css     Manually compile CSS, only.
# rake js      Manually compile JS, only.
```

## Afterthoughts

### Updating `facebook.github.io/react`

The easiest way to do this is to have a separate clone of this repository, checked out to the `gh-pages` branch. We have a build step that expects this to be in a directory named `react-gh-pages` at the same depth as `react`. Then it's just a matter of running `grunt docs`, which will compile the site and copy it out to this repository. From there you can check it in.

**Note:** This should only be done for new releases. You should create a tag corresponding to the relase tag in the main repository.

### Removing the Jekyll / Ruby Dependency

In an ideal world, we would not be adding a Ruby dependency on part of our project. We would like to move towards a point where we are using React to render the website.
