Add documentation on 'getting up and running'

Some hopefully usefully instructions to help people get up and running.

Re: Issue #34 On my machine I didn't need to install memcached to successfully install the local requirements.

Re: Issue #39 I've linked to this issue for now. It would be good to remove the need for those steps and then this link can be removed.

+Getting up and running
+----------------------
 
+The steps below will get you up and running with a local development environment. We assume you have the following installed:
+
+* pip
+* virtualenv
+* PostgreSQL
+
+First make sure to create and activate a virtualenv, then open a terminal at the project root and install the requirements for local development::
+
+    $ pip install -r requirements/local.txt
+
+You can now run the usual Django ``runserver`` command (replace ``yourapp`` with the name of the directory containing the Django project)::
+
+    $ python yourapp/manage.py runserver
+
+The base app will run but you'll need to carry out a few steps to make the sign-up and login forms work. These are currently detailed in `issue #39`_.

+
+**Live reloading and Sass CSS compilation**
+
+If you'd like to take advantage of live reloading and Sass / Compass CSS compilation you can do so with the included Grunt task.
+
+Make sure that nodejs_ is installed. Then in the project root run::
+
+    $ npm install
+
+.. _nodejs: http://nodejs.org/download/ 
+
+Now you just need::
+
+    $ grunt serve
+
+The base app will now run as it would with the usual ``manage.py runserver`` but with live reloading and Sass compilation enabled.
+
+To get live reloading to work you'll probably need to install an `appropriate browser extension`_
