+
+Python dependencies can be installed via `pip` using the `requirements.txt` provided in this project
+
+```bash
+pip install -r ./requirements.txt 
+
+```
+Ansible dependencies can be installed via `ansible-galaxy` using the `requirements.yaml` provided in this project.
+
+```bash
+ansible-galaxy install -r ./requirements.yaml
+```
+
+Required project dependencies are generally pinned to known working or stable versions to ensure users have a smooth initial experience. In some cases it may be required to change the default version of a dependency. In such cases users are welcome to experiment with alternate versions, however compatibility may not be guaranteed.
+
+# Docker
+
+If you are standing up your infrastructure via a Docker image created from the [Dockerfile](../../Dockerfile) overriding a dependency version can be accomplished by supplying one or more docker build arguments:
+
+| ARG               | NOTE                              |
+|-------------------|-----------------------------------|
+| HELM_VERSION      | the version of helm to install    |
+| KUBECTL_VERSION   | the version of kubectl to install |
+| TERRAFORM_VERSION | the version terraform to install  |
+
+Example of using build arguments to control specific versions of dependencies installed within the Docker image :
+```bash
+# Override kubectl version
+docker build \
+	--build-arg KUBECTL_VERSION=1.27.9 \
+	-t viya4-iac-k8s .
+```
+
+# Install Script
+
+If deploying via the [installation script](./ScriptUsage.md) you can modify the dependency requirements files for python and ansible respectively:
+
+| FILE              | FOR                             |
+|-------------------|---------------------------------|
+| requirements.txt  | dependencies for python         |
+| requirements.yaml | dependencies for ansible-galaxy |
