+This directory contains scripts and other resources for instantiating a
+Veraison deployment in AWS. The deployment is a CloudFormation stack with a
+node running Veraison services, another node running Keycloak authentication,
+and an RDS Postgres instance serving as the key-value store.
+
+## Dependencies
+
+This deployment depends on the `debian` deployment (which, in turn, depends on
+the `native` deployment). Please see [its
+README](../debian/README.md#dependencies) for the dependencies list.
+
+Additionally, the following dependencies are required specifically for AWS deployment:
+
+- `curl`: used to transfer the Debian package to the EC2 node.
+- `openssl`: used to generate TLS certs (note: unlike with `native` deployment,
+  where pre-generated certs may optionally be used, cert generation is mandatory
+  for this deployment, as the certs must be specific to the created EC2 instance).
+- `packer`: used to build AMI images using temporary EC2 instances.
+- `psql`: Postgres client used to initialise the stores (may be packaged on its
+  own or as part of `postgres`, depending on the platform).
+- A number of Python packages used by the deployment script. Please see
+  [requirements.txt](misc/requirements.txt) for details.
+
+`curl` and `openssl` should be available from your OS's package manager. Python
+dependencies are installable via `pip`/`PyPI`. For `packer`, please see [its
+documentation](https://developer.hashicorp.com/packer/tutorials/aws-get-started/get-started-install-cli).
+
+### Bootstrap
+
+To simplify dependency installation, the deployment script implements bootstrap
+for Arch, Ubuntu, and MacOSX (using [homebrew](https://brew.sh)). 
+
+```bash
+git clone https://github.com/veraison/services.git
+cd services/deployments/aws
+
+make bootstrap
+```
+
+(this will only work on the above-mentioned platforms).
+
+### AWS account
+
+Finally, you need an existing AWS account, that has at least one VPC with at
+least two subnets (at least one of which is public) configured.
+
+Please see [boto3
+documentation](https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html)
+for how to configure `aws` CLI to access this account.
+
+
+## Working with the deployment
+
+Before creating a deployment, you need to provide account-specific
+configuration that specifies the IDs of the VPC and subnets that will be used
+for the deployment as well as the CIDR that will be granted access to the
+deployment. Please use [misc/arm.cfg](misc/arm.cfg) for an example.
+
+Once the account-specific config file is created, define `AWS_ACCOUNT_CFG`
+environment variable to point to it and execute `make deploy` to create the
+deployment.
+
+```bash
+export AWS_ACCOUNT_CFG=misc/arm.cfg  # replace with path to your config
+make deploy
+```
+
+Deployment can be accessed via CLI front end:
+
+```bash
+source env/env.bash  # for bash, or alternatively, env/env.zsh for Zsh users
+veraison status
+```
+
+This should display the DNS name and IP address of the instance and show
+Veraison services as active and running.
+
+To make sure the deployment works, you can run through
+[end-to-end](../../end-to-end/README.md) flow.
+
+For example 
+
+```bash
+# env/env.bash must be sourced
+../../end-to-end/end-to-end-aws provision
+# followed by
+../../end-to-end/end-to-end-aws verify rp
+# followed by
+```
+
+Finally, to remove the deployment, you can run
+
+```bash
+make really-clean
+```
