 Ironic
 ======
 
-Provision Bare Metal machines with Nova.
+Ironic is an Incubated OpenStack project which aims to provision
+bare metal machines instead of virtual machines, forked from the
+Nova Baremetal driver.
+
+-----------------
+Project Resources
+-----------------
+
+Project status, bugs, and blueprints are tracked on Launchpad:
+
+  http://launchpad.net/ironic
+
+Additional resources are linked from the project wiki page:
+
+  https://wiki.openstack.org/wiki/Ironic
+
+Developers wishing to contribute to an OpenStack project should
+find plenty of helpful resources here:
+
+  https://wiki.openstack.org/wiki/Getting_Started
+
+All OpenStack projects use Gerrit for code reviews.
+A good reference for that is here:
+
+  https://wiki.openstack.org/wiki/GerritWorkflow
+
+--------------------
+Project Architecture
+--------------------
+
+An Ironic deployment will be composed of the following components:
+
+- A **RESTful API** service, by which operators and other services
+  may interact with the managed bare metal servers.
+- A **Manager** service, which does the bulk of the work. Functionality
+  is exposed via the API service.
+  The Manager and API services communicate via RPC.
+- An internal **driver API** for different Manager functions.
+  There are currently two driver types: BMCDriver and DeploymentDriver.
+- Internal drivers for each function are dynamically loaded, according to the
+  specific hardware being managed, such that heterogeneous hardware deployments
+  can be managed by a single Manager service.
+- One or more **Deployment Agents**, which provide local control over
+  the hardware which is not available remotely to the Manager.
+  A ramdisk should be built which contains one of these agents, eg. with
+  https://github.com/stackforge/diskimage-builder, and this ramdisk can be
+  booted on-demand. The agent is never run inside a tenant instance.
+- A **Database** and a DB API for storing persistent state of the Manager and Drivers.
+
+-----------
+Development
+-----------
+
+Ironic source code should be pulled directly from git::
+
+  git clone https://github.com/openstack/ironic
+
+Setting up a local environment for development can be done with tox::
+
+    cd <your_src_dir>/ironic
+
+    # install prerequisites
+    sudo apt-get install python-dev swig libssl-dev python-pip
+    sudo easy_install nose
+    sudo pip install virtualenv setuptools-git flake8
+
+    # create virtualenv
+    tox -evenv -- echo 'done'
+
+    # activate the virtualenv
+    source .tox/venv/bin/activate
+
+    # run pep8/flake8 checks
+    flake8
+
+    # run unit tests
+    testr run
+
+    # deactivate the virtualenv
+    deactivate
+
