 # eoapi-template
+
 Demonstration application showing the use and configuration options of the [eoapi-cdk constructs](https://github.com/developmentseed/eoapi-cdk) on AWS.
+
+## Requirements
+
+- python
+- docker
+- the AWS CDK CLI
+- AWS credentials environment variables configured to point to an account. 
+- **Optional** a `config.yaml` file to override the default deployment settings defined in `config.py`.
+
+## Installation
+
+```
+python -m venv .venv
+source .venv/bin/activate
+python -m pip install -r requirements.txt
+```
+
+## Deployment
+
+First, synthesize the app 
+
+```
+cdk synth --all
+```
+
+Then, deploy
+
+```
+cdk deploy --all --require-approval never
+```
