+Running Locally
+===============
 
+$ GYP_GENERATORS=ninja  ./gyp_skia  gyp/webtry.gyp gyp/most.gyp -Dskia_gpu=0
+$ ninja -C out/Debug webtry
 $ cd experimental/webtry
-$ python server.py

+Only tested under linux, doubtful it will work on other platforms.
+
+Full Server Setup
+=================
+
+Create a GCE instance:
+
+gcutil --project=google.com:skia-buildbots addinstance skia-webtry-b \
+  --zone=us-central2-b --external_ip_address=108.170.220.126 \
+  --service_account=default \
+  --service_account_scopes="https://www.googleapis.com/auth/devstorage.full_control" \
+  --network=default --machine_type=n1-standard-1 --image=backports-debian-7-wheezy-v20140331 \
+  --persistent_boot_disk
+
+SSH into the instance:
+
+  gcutil --project=google.com:skia-buildbots ssh --ssh_user=default skia-webtry-b
+
+
+The following things only need to be done once
+----------------------------------------------
+
+1. sudo apt-get install git schroot debootstrap
+2. git clone https://skia.googlesource.com/skia
+3. Add the following to /etc/fstab and reboot:
+
+  none /dev/shm tmpfs rw,nosuid,nodev,noexec 0 0
+
+The above will allow ninja to run. See http://stackoverflow.com/questions/2009278/python-multiprocessing-permission-denied
+
+4. Add the following to the /etc/schroot/minimal/fstab:
+
+  /home/webtry/inout             /inout  none    rw,bind         0       0
+
+5. Change /etc/monit/monitrc to:
+
+  set daemon 2
+
+then run the following so it applies:
+
+  sudo /etc/init.d/monit restart
+
+This means that monit will poll every two seconds that our application is up and running.
+
+Do the following the first time you setup a machine, and each time you want to update the code running on the server
+--------------------------------------------------------------------------------------------------------------------
+
+cd ~/skia/experimental/webtry/setup
+./webtry_setup.sh
+
+
+Do these steps only once, but only after running webtry_setup.sh the first time
+-------------------------------------------------------------------------------
+
+1. sudo debootstrap --variant=minbase wheezy /srv/chroot/webtry
