 ## General Workflow
 
 - fork/clone repo
-- create an infrastructure configuration in the `prepare-vms/infra` directory
-  (using one of the example files in that directory)
+- set required environment variables
 - create your own setting file from `settings/example.yaml`
 - if necessary, increase allowed open files: `ulimit -Sn 10000`
-- run `./workshopctl start` to create instances
-- run `./workshopctl deploy` to install Docker and setup environment
-- run `./workshopctl kube` (if you want to install and setup Kubernetes)
-- run `./workshopctl cards` (if you want to generate PDF for printing handouts of each users host IP's and login info)
-- run `./workshopctl stop` at the end of the workshop to terminate instances
+- run `./workshopctl` commands to create instances, install docker, setup each users environment in node1, other management tasks
+- run `./workshopctl cards` command to generate PDF for printing handouts of each users host IP's and login info
 
 ## Clone/Fork the Repo, and Build the Tools Image
 
 The Docker Compose file here is used to build a image with all the dependencies to run the `./workshopctl` commands and optional tools. Each run of the script will check if you have those dependencies locally on your host, and will only use the container if you're [missing a dependency](workshopctl#L5).

 - Using a non-default VPC or Security Group isn't supported out of box yet, so you will have to customize `lib/commands.sh` if you want to change that.
 - These instances will assign the default VPC Security Group, which does not open any ports from Internet by default. So you'll need to add Inbound rules for `SSH | TCP | 22 | 0.0.0.0/0` and `Custom TCP Rule | TCP | 8000 - 8002 | 0.0.0.0/0`, or run `./workshopctl opensg` which opens up all ports.
 
-### Create your `infra` file

-You need to do this only once. (On AWS, you can create one `infra`
-file per region.)
+- `AWS_ACCESS_KEY_ID`
+- `AWS_SECRET_ACCESS_KEY`
+- `AWS_DEFAULT_REGION`
 
-Make a copy of one of the example files in the `infra` directory.
+If you're not using AWS, set these to placeholder values:
 
-For instance:
-
-```bash
-cp infra/example.aws infra/aws-us-west-2
 ```
-
-Edit your infrastructure file to customize it.
-You will probably need to put your cloud provider credentials,
-select region...
+export AWS_ACCESS_KEY_ID="foo"
+export AWS_SECRET_ACCESS_KEY="foo"
+export AWS_DEFAULT_REGION="foo"
+```
 
 If you don't have the `aws` CLI installed, you will get a warning that it's a missing dependency. If you're not using AWS you can ignore this.
 
-### Create your `settings` file
+### Update/copy `settings/example.yaml`
 
-Similarly, pick one of the files in `settings` and copy it
-to customize it.
+Then pass `settings/YOUR_WORKSHOP_NAME-settings.yaml` as an argument to `./workshopctl deploy`, `./workshopctl cards`, etc.
 
-For instance:

 ### Example Steps to Configure Instances from a non-AWS Source
 
-- Copy `infra/example.generic` to `infra/generic`
-- Run `./workshopctl start --infra infra/generic --settings settings/...yaml`
-- Note the `prepare-vms/tags/TAG/` path that has been auto-created.
-- Launch instances via your preferred method. You'll need to get the instance IPs and be able to SSH into them.
-- Edit the file `prepare-vms/tags/TAG/ips.txt`, it should list the IP addresses of the VMs (one per line, without any comments or other info)
-- Continue deployment of cluster configuration with `./workshopctl deploy TAG`
-- Optionally, configure Kubernetes clusters of the size in the settings: workshopctl kube `TAG`
-- Optionally, test your Kubernetes clusters. They may take a little time to become ready: workshopctl kubetest `TAG`
-- Generate cards to print and hand out: workshopctl cards `TAG`
-- Print the cards file: prepare-vms/tags/`TAG`/ips.html
+- Launch instances via your preferred method. You'll need to get the instance IPs and be able to ssh into them.
+- Set placeholder values for [AWS environment variable settings](#required-environment-variables).
+- Choose a tag. It could be an event name, datestamp, etc. Ensure you have created a directory for your tag: `prepare-vms/tags/<tag>/`
+- If you have not already generated a file with the IPs to be configured:
+  - The file should be named `prepare-vms/tags/<tag>/ips.txt`
+  - Format is one IP per line, no other info needed.
+- Ensure the settings file is as desired (especially the number of nodes): `prepare-vms/settings/kube101.yaml`
+- For a tag called `myworkshop`, configure instances: `workshopctl deploy myworkshop settings/kube101.yaml`
+- Optionally, configure Kubernetes clusters of the size in the settings: `workshopctl kube myworkshop`
+- Optionally, test your Kubernetes clusters. They may take a little time to become ready: `workshopctl kubetest myworkshop`

-## Be careful with `chown`, `chmod`, `mv`
-
-* Layers cannot store efficiently changes in permissions or ownership.
-
-* Layers cannot represent efficiently when a file is moved either.
-
-* As a result, operations like `chown`, `chown`, `mv` can be expensive.
-
-* For instance, in the Dockerfile snippet below, each `RUN` line
-  creates a layer with an entire copy of `some-file`.
-
-  ```dockerfile
-  COPY some-file .
-  RUN chown www-data:www-data some-file
-  RUN chmod 644 some-file
-  RUN mv some-file /var/www
-  ```
-
-* How can we avoid that?
-
----
-
-## Put files on the right place
-
-* Instead of using `mv`, directly put files at the right place.
-
-* When extracting archives (tar, zip...), merge operations in a single layer.
-
-  Example:
-
-  ```dockerfile
-    ...
-    RUN wget http://.../foo.tar.gz \
-     && tar -zxf foo.tar.gz \
-     && mv foo/fooctl /usr/local/bin \
-     && rm -rf foo
-  ...
-  ```
-
----
-
-## Use `COPY --chown`
-
-* The Dockerfile instruction `COPY` can take a `--chown` parameter.
-
-  Examples:
-
-  ```dockerfile
-  ...
-  COPY --chown=1000 some-file .
-  COPY --chown=1000:1000 some-file .
-  COPY --chown=www-data:www-data some-file .
-  ```
-
-* The `--chown` flag can specify a user, or a user:group pair.
-
-* The user and group can be specified as names or numbers.
-
-* When using names, the names must exist in `/etc/passwd` or `/etc/group`.
-
-  *(In the container, not on the host!)*
-
----
-
-## Set correct permissions locally
-
-* Instead of using `chmod`, set the right file permissions locally.
-
-* When files are copied with `COPY`, permissions are preserved.
-

-## Pets vs. Cattle

-* In the "pets vs. cattle" metaphor, there are two kinds of servers.
-
-* Pets:
-
-  * have distinctive names and unique configurations
-
-  * when they have an outage, we do everything we can to fix them
-
-* Cattle:
-
-  * have generic names (e.g. with numbers) and generic configuration

-## Local development environments
-
-* When we use local VMs (with e.g. VirtualBox or VMware), our workflow looks like this:
-
-  * create VM from base template (Ubuntu, CentOS...)
-
-  * install packages, set up environment
-
-  * work on project
-
-  * when done, shut down VM
-
-  * next time we need to work on project, restart VM as we left it
-
-  * if we need to tweak the environment, we do it live
-
-* Over time, the VM configuration evolves, diverges.
-
-* We don't have a clean, reliable, deterministic way to provision that environment.

-## Local development with Docker
-
-* With Docker, the workflow looks like this:
-
-  * create container image with our dev environment
-
-  * run container with that image
-
-  * work on project
-
-  * when done, shut down container
-
-  * next time we need to work on project, start a new container
-
-  * if we need to tweak the environment, we create a new image

-* We have a clear definition of our environment, and can share it reliably with others.
