 This is a wrapper CDK code that is used to test a deployment of the `eoapi-cdk` constructs.
 
 ## Requirements
 
-- python
+- [uv](https://docs.astral.sh/uv/getting-started/installation/)
 - docker
 - node
 - AWS credentials environment variables configured to point to an account.
 
 ## Installation
 
-Install python dependencies with
+From the top level of this repository, install **eoapi-cdk**:
 
-```
-python -m venv .venv
+```sh
+npm run install:all
+npm run build
+npm run package
+uv sync --group deploy
+uv pip install dist/python/*.gz
 source .venv/bin/activate
-python -m pip install -r requirements.txt
-```
-
-Install the latest `eoapi-cdk` either from PyPI:
-
-```
-pip install eoapi-cdk
 ```
 
-Or alternatively, compile and package from the root of this repository to get the python version of the constructs locally.
+Then, go to the integration deploy directory:
 
-Also install node dependencies with
-
-```
+```sh
+cd integration_tests/cdk
 npm install
 ```
 
 Verify that the `cdk` CLI is available. Since `aws-cdk` is installed as a local dependency, you can use the `npx` node package runner tool, that comes with `npm`.
 
-```
+```sh
 npx cdk --version
 ```
 
 ## Deployment
 
 First, synthesize the app
 
-```
+```sh
 npx cdk synth --all
 ```
 
 Then, deploy
 
-```
+```sh
 npx cdk deploy --all --require-approval never
 ```
