+
+== Pain test ==
+Before you begin, check to see if your CPU supports virtualization:
+
+{{{
+egrep '(vmx|svm)' /proc/cpuinfo
+}}}
+
+If that commands returns nothing, you are in for a painful ride. Development will be really slow and possibly not worth it.
+
+Hopefull, you will instead see something like:
+
+{{{
+0 jamie@chicken:puppet$  egrep '(vmx|svm)' /proc/cpuinfo

+0 jamie@chicken:puppet$
+}}}
+
+== Setting up your directory structure ==
+
+Be sure you have at least 2GB of space available on your disk.
+
+Here's a sample directory layout:
+
+ * confdir - put the MFPL git repo here (e.g. `git clone gitosis@git.mayfirst.org/mfpl/puppet confdir`)
+
+ * images - download (link coming soon) into your images directory. Don't gunzip right away! Instead, make a backup copy (so you don't have to re-download it if you mess it up), then gunzip it.
+
+ * modules - this is where I git checkout puppet modules from other puppet developers before adding them to our repository.
+
+== Launching your virtual image
+
+Be sure you have the qemu-kvm package installed.
+
+You can start your virtual image with:
+
+{{{
+screen kvm -hda images/roach.qcow -m 512 -net nic -net user,hostfwd=tcp::2222-:22 -nographic
+}}}
+
+This should put you into a screen session, allowing you to watch the boot process. You can detach with `ctl-a d` and re-attach with screen -x.
+
+You can login with root (no password).
+
+After logging in, set the root password by typing:
+
+{{{
+passwd
+}}}
+
+Then, you can exit and detach from the screen session.
+
+The kvm command sets up very simple networking, with port 2222 on our localhost forwarded to port 22 on roach.
+
+Add the following to your ~/.ssh/config file:
+
+{{{
+Host roach
+Hostname localhost
+Port 2222
+User root
+}}}
+
+Now, you should be able to ssh into your host with:
+
+{{{
+ssh root@roach
+}}}
+
+== Bootstrapping your puppet configuration ==
+
+You are now ready for your first puppet push.
+
+Begin in your confdir. Add a remote for roach:
+
+{{{
+git remote add roach root@roach:/etc/puppet-bare
+}}}
+
+Next, push into roach:
+
+{{{
+git push roach master
+}}}
