README.md

+This is edX, a platform for online course delivery. The project is primarily
+written in [Python](http://python.org/), using the
+[Django](https://www.djangoproject.com/) framework. We also use some
+[Ruby](http://www.ruby-lang.org/) and some [NodeJS](http://nodejs.org/).
+
+Installation
+============
+The installation process is a bit messy at the moment. Here's a high-level
+overview of what you should do to get started.
+
+**TLDR:** There is a `create-dev-env.sh` script that will attempt to set all
+of this up for you. If you're in a hurry, run that script. Otherwise, I suggest
+that you understand what the script is doing, and why, by reading this document.
+
+Directory Hierarchy
+-------------------
+This code assumes that it is checked out in a directory that has three sibling
+directories: `data` (used for XML course data), `db` (used to hold a
+[sqlite](https://sqlite.org/) database), and `log` (used to hold logs). If you
+clone the repository into a directory called `edx` inside of a directory
+called `dev`, here's an example of how the directory hierarchy should look:
+
+    * dev
+     \
+      * data
+      * db
+      * log
+      * edx
+       \
+        README.md
+
+Language Runtimes
+-----------------
+You'll need to be sure that you have Python 2.7, Ruby 1.9.3, and NodeJS
+(latest stable) installed on your system. Some of these you can install
+using your system's package manager: [homebrew](http://mxcl.github.io/homebrew/)
+for Mac, [apt](http://wiki.debian.org/Apt) for Debian-based systems
+(including Ubuntu), [rpm](http://www.rpm.org/) or [yum](http://yum.baseurl.org/)
+for Red Hat based systems (including CentOS).
+
+If your system's package manager gives you the wrong version of a language
+runtime, then you'll need to use a versioning tool to install the correct version.
+Usually, you'll need to do this for Ruby: you can use
+[`rbenv`](https://github.com/sstephenson/rbenv) or [`rvm`](https://rvm.io/), but
+typically `rbenv` is simpler. For Python, you can use
+[`pythonz`](http://saghul.github.io/pythonz/),
+and for Node, you can use [`nvm`](https://github.com/creationix/nvm).
+
+Virtual Environments
+--------------------
+Often, different projects will have conflicting dependencies: for example, two
+projects depending on two different, incompatible versions of a library. Clearly,
+you can't have both versions installed and used on your machine simultaneously.
+Virtual environments were created to solve this problem: by installing libraries
+into an isolated environment, only projects that live inside the environment
+will be able to see and use those libraries. Got incompatible dependencies? Use
+different virtual environments, and your problem is solved.
+
+Remember, each language has a different implementation. Python has
+[`virtualenv`](http://www.virtualenv.org/), Ruby has
+[`bundler`](http://gembundler.com/), and Node's virtual environment support
+is built into [`npm`](https://npmjs.org/), its library management tool.
+For each language, decide if you want to use a virtual environment, or if you
+want to install all the language dependencies globally (and risk conflicts).
+I suggest you start with installing things globally until and unless things
+break; you can always switch over to a virtual environment later on.
+
+Language Packages
+-----------------
+The Python libraries we use are listed in `requirements.txt`. The Ruby libraries
+we use are listed in `Gemfile`. The Node libraries we use are listed in
+`packages.json`. Python has a library installer called
+[`pip`](http://www.pip-installer.org/), Ruby has a library installer called
+[`gem`](https://rubygems.org/) (or `bundle` if you're using a virtual
+environment), and Node has a library installer called
+[`npm`](https://npmjs.org/).
+Once you've got your languages and virtual environments set up, install
+the libraries like so:
+
+    $ pip install -r pre-requirements.txt
+    $ pip install -r requirements.txt
+    $ bundle install
+    $ npm install
+
+Other Dependencies
+------------------
+You'll also need to install [MongoDB](http://www.mongodb.org/), since our
+application uses it in addition to sqlite. You can install it through your
+system package manager, and I suggest that you configure it to start
+automatically when you boot up your system, so that you never have to worry
+about it again. For Mac, use
+[`launchd`](https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man8/launchd.8.html)
+(running `brew info mongodb` will give you some commands you can copy-paste.)
+For Linux, you can use [`upstart`](http://upstart.ubuntu.com/), `chkconfig`,
+or any other process management tool.
+
+Configuring Your Project
+------------------------
+We use [`rake`](http://rake.rubyforge.org/) to execute common tasks in our
+project. The `rake` tasks are defined in the `rakefile`, or you can run `rake -T`
+to view a summary.
+
+Before you run your project, you need to create a sqlite database, create
+tables in that database, run database migrations, and populate templates for
+CMS templates. Fortunately, `rake` will do all of this for you! Just run:
+
+    $ rake django-admin[syncdb]
+    $ rake django-admin[migrate]
+    $ rake django-admin[update_templates]
+
+If you are running these commands using the [`zsh`](http://www.zsh.org/) shell,
+zsh will assume that you are doing
+[shell globbing](https://en.wikipedia.org/wiki/Glob_(programming)), search for
+a file in your directory named `django-adminsyncdb` or `django-adminmigrate`,
+and fail. To fix this, just surround the argument with quotation marks, so that
+you're running `rake "django-admin[syncdb]"`.
+
+Run Your Project
+----------------
+edX has two components: Studio, the course authoring system; and the LMS
+(learning management system) used by students. These two systems communicate
+through the MongoDB database, which stores course information.
+
+To run Studio, run:
+
+    $ rake cms
+
+To run the LMS, run:
+
+    $ rake lms[cms.dev]
+
+Studio runs on port 8001, while LMS runs on port 8000, so you can run both of
+these commands simultaneously, using two different terminal windows. To view
+Studio, visit `127.0.0.1:8001` in your web browser; to view the LMS, visit
+`127.0.0.1:8000`.
+
+There's also an older version of the LMS that saves its information in XML files
+in the `data` directory, instead of in Mongo. To run this older version, run:
+
+$ rake lms
+
+Further Documentation
+=====================
+Once you've got your project up and running, you can check out the `docs`
+directory to see more documentation about how edX is structured.

-    <p>EPFL is one of the two Swiss Federal Institutes of Technology. With the status of a national school since 1969, the young engineering school has grown in many dimensions, to the extent of becoming one of the most famous European institutions of science and technology. It has three core missions: training, research and technology transfer. </p>
 
- <p>EPFL is located in Lausanne in Switzerland, on the shores of the largest lake in Europe, Lake Geneva and at the foot of the Alps and Mont-Blanc. Its main campus brings together over 11,000 persons, students, researchers and staff in the same magical place. Because of its dynamism and rich student community, EPFL has been able to create a special spirit imbued with curiosity and simplicity. Daily interactions amongst students, researchers and entrepreneurs on campus give rise to new scientific, technological and architectural projects.
-</p>
+<p>EPFL is the Swiss Federal Institute of Technology in Lausanne. The past decade has seen EPFL ascend to the very top of European institutions of science and technology: it is ranked #1 in Europe in the field of engineering by the Times Higher Education (based on publications and citations), Leiden Rankings, and the Academic Ranking of World Universities.</p>
+
+<p>EPFL's main campus brings together 12,600 students, faculty, researchers, and staff in a high-energy, dynamic learning and research environment. It directs the Human Brain Project, an undertaking to simulate the entire human brain using supercomputers, in order to gain new insights into how it operates and to better diagnose brain disorders. The university is building Solar Impulse, a long-range solar-powered plane that aims to be the first piloted fixed-wing aircraft to circumnavigate the Earth using only solar power. EPFL was part of the Alinghi project, developing advanced racing boats that won the America's Cup multiple times. The university operates, for education and research purposes, a Tokamak nuclear fusion reactor. EPFL also houses the Musée Bolo museum and hosts several music festivals, including Balelec, that draws over 15,000 guests every year.</p>
+
+<p>EPFL is a major force in entrepreneurship, with 2012 bringing in $100M in funding for ten EPFL startups. Both young spin-offs (like Typesafe and Pix4D) and companies that have long grown past the startup stage (like Logitech) actively transfer the results of EPFL's scientific innovation to industry.</p>
