+Teuthology Lab Setup Notes
+==========================
+
+Introduction
+============
+
+We recently set up a new lab for Ceph testing and decided to document the parts of the process that are most relevant to teuthology. This is the result.
+
+We started by setting aside two of the test machines: one as the 'teuthology node', and another as the 'paddles/pulpito node'. These would be used to orchestrate automated testing and to store and serve the results on our intranet.
+
+paddles/pulpito node
+====================
+
+We're currently running both paddles and pulpito on the same node. We have a proxy server up front listening on port 80 that forwards to the proper service based on which hostname is used. Feel free to modify our `paddles <docs/reference/nginx_paddles>`_ and `pulpito <docs/reference/nginx_pulpito>`_ configurations for your use.
+
+Do the following as root or as another user with sudo access::
+
+    sudo apt-get install git python-dev python-virtualenv postgresql postgresql-contrib postgresql-server-dev-all supervisor
+    sudo -u postgres createuser paddles -P
+    sudo -u postgres createdb paddles
+
+Create a separate user for paddles and puplito. We used 'paddles' and 'pulpito'.
+
+
+paddles
+-------
+Follow instructions at https://github.com/ceph/paddles/blob/master/README.rst
+
+
+pulpito
+-------
+Follow instructions at https://github.com/ceph/pulpito/blob/master/README.rst
+
+
+Starting up
+-----------
+
+Back as the 'root or sudo' user::
+
+    sudo cp ~paddles/paddles/supervisord_paddles.conf /etc/supervisor/conf.d/paddles.conf
+    sudo supervisorctl reread && sudo supervisorctl update paddles && sudo supervisorctl start paddles
+    sudo cp ~pulpito/pulpito/supervisord_pulpito.conf /etc/supervisor/conf.d/pulpito.conf
+    sudo supervisorctl reread && sudo supervisorctl update pulpito && sudo supervisorctl start pulpito
+
+
+Test Nodes
+==========
+
+Each node needs to have a user named 'ubuntu' with passwordless sudo access.
+
+It's also necessary to generate an ssh key pair that will be used to provide
+passwordless authentication to all the test nodes, and put the public key in
+``~/.ssh/authorized_keys`` on all the test nodes.
+
+
+Teuthology Node
+===============
+
+Create an ``/etc/teuthology.yaml`` that looks like::
+
+    lab_domain: example.com
+    lock_server: http://pulpito.example.com:8080
+    results_server: http://pulpito.example.com:8080
+    queue_host: localhost
+    queue_port: 11300
+    results_email: you@example.com
+    archive_base: /home/teuthworker/archive
+
+Do the following as root or as another user with sudo access:
+
+Create two additional users: one that simply submits jobs to the queue, and
+another that picks them up from the queue and executes them. We use
+'teuthology' and 'teuthworker', respectively.
+
+Give both users passwordless sudo access.
+
+Copy the ssh key pair that you created to access the test nodes into each of
+these users' ``~/.ssh`` directory.
+
+Install these packages::
+
+    sudo apt-get -y install git python-dev python-pip python-virtualenv libevent-dev python-libvirt beanstalkd
+
+Now, set up the two users you just created:
+
+
+Scheduler
+---------
+As 'teuthology', do the following::
+
+    mkdir ~/src
+    git clone https://github.com/ceph/teuthology.git src/teuthology_master
+    pushd src/teuthology_master/
+    ./bootstrap
+    popd
+
+
+Worker
+------
+As 'teuthworker', do the following::
+
+    mkdir ~/src
+    git clone https://github.com/ceph/teuthology.git src/teuthology_master
+    pushd src/teuthology_master/
+    ./bootstrap
+    popd
+    mkdir ~/bin
+    wget -O ~/bin/worker_start https://raw.githubusercontent.com/ceph/teuthology/docs/docs/reference/worker_start.sh
+    echo 'PATH="$HOME/src/teuthology_master/virtualenv/bin:$PATH"' >> ~/.profile
+    source ~/.profile
+    mkdir -p ~/archive/worker_logs
+    worker_start magna 1
+
+
+Submitting Nodes
+================
+
+First::
+
+    wget https://raw.githubusercontent.com/ceph/teuthology/docs/docs/reference/create_nodes.py
+
+Edit ``create_nodes.py`` to generate the hostnames of the machines you want to submit to paddles.
+
+Now to do the work::
+
+    python create_nodes.py
+    teuthology-lock --owner initial@setup --list-targets > /tmp/targets
+    teuthology --owner initial@setup /tmp/targets
+    teuthology-lock --owner initial@setup --unlock -t /tmp/targets
+
+
+Serving Test Logs
+=================
+
+pulpito tries to provide links to test logs. Out-of-the-box, those links will be broken, but are easy to fix. 
+
+First, install your favorite web server on the teuthology node. If you use nginx, you may use `our configuration <docs/reference/nginx_test_logs>`_ as a template.
+
+Once you've got log files being served, edit paddles' ``config.py`` and update the ``job_log_href_templ`` value. Restart paddles when you're done.
