+### Capture Full Log of Route 27 at Powell
+
+Deploys an EC2 box that  checks each minute the position, speed,
+orientation and predicted arrival of route 27. This bus has messed
+with me one too many times and now it's time to get even.
+
+1. Sign up for Amazon Web Services free tier [here](http://aws.amazon.com/free/).
+    It is **extremely important** to ensure the region in your
+    Amazon Web Console is set to "N. California" as the defaults 
+    are all configured to use this region in future steps. If you decide
+    to use a different region you will need to specify the region in future
+    steps when noted.
+
+2. Create Amazon IAM credentials for deployment.
+    Assuming you are signed into the AWS console, visit the [user
+    admin](https://console.aws.amazon.com/iam/home#users) page. Create
+    a new user and note their security credentials (ID and secret key).
+    Then attach a user policy of "Power User" to the newly created user.
+
+3. [Create EC2 keypair](https://console.aws.amazon.com/ec2/v2/home?region=us-west-1#KeyPairs:sort=keyName).
+
+4. Clone this repo including its chef recipe submodules.
+    ```bash
+    git clone --recursive https://github.com/begriffs/microservice-template.git
+    ```
+
+5. Install <a href="https://www.packer.io/" target="_blank">Packer</a>.
+    On a Mac you can use homebrew:
+    ```bash
+    brew tap homebrew/binary
+    brew install packer
+    ```
+6. Build the AMI
+    ```bash
+    packer build -var 'aws_access_key=xxx' -var 'aws_secret_key=xxx' stalker.json
+    ```
+
+7. Launch the AMI from the Amazon Web Console. Then go watch the
+   files accumulate on your S3 bucket.
