Add a proper README file

README.md

-My super web application
-========================
+A simple web application: URL follower
+======================================
 
-I'll write more about this when it's ready...
+This is a simple web application which allows users to generate
+short tracked URLS from longer ones.  A short URL redirects to
+the original URL, when followed.  It is tracked in the sense that
+a counter is incremented, every time the URL is followed.
+
+
+Installation
+------------
+
+Assuming you have a working Python 2.x and `virtualenv`, clone
+the repository and then type:
+
+```sh
+virtualenv --no-site-packages venv
+source venv/bin/activate.csh
+pip install -r requirements.txt
+```
+
+Then prepare the database:
+
+```sh
+python manage.py migrate
+```
+
+To deploy the server:
+
+```sh
+python manage.py runserver
+```
+
+and then go to [http://localhost:8000/](http://localhost:8000/).
+
+
+Step by step
+------------
+
+A better description of how to arrive here one step at a time,
+from scratch, is found in the README file in branch `prepare`.
+
+Otherwise, just follow the commits, in exactly the order we
+showed them in the lab on Monday, June 15, 2015.
