-## Requirements
+## Role Requirements
 
-### NGINX Plus (Optional)
+### NGINX
 
-If you wish to install NGINX Plus using this role, you will need to obtain an NGINX Plus license beforehand. *You do not need to do anything beforehand if you want to install NGINX OSS.*
+Depending on your target NGINX use case, you might need to obtain a license or API key/token before being able to use the role:
+
+| Product | Requirements |
+|---------|--------------|
+| NGINX | None |
+| NGINX Plus | NGINX Plus license (both a license key and crt files) |
+| NGINX Agent | A compatible control plane and (optionally) an NGINX One SaaS console data plane token |
+| NGINX Amplify | API key found within the NGINX Amplify SaaS console |
 
 ### Ansible
 
-- This role is developed and tested with [maintained](https://docs.ansible.com/ansible/devel/reference_appendices/release_and_maintenance.html) versions of Ansible core (above `2.12`).
-- When using Ansible core, you will also need to install the following collections:
-
-    ```yaml
-    ---
-    collections:
-      - name: ansible.posix
-        version: 1.5.4
-      - name: community.general
-        version: 9.0.1
-      - name: community.crypto # Only required if you plan to install NGINX Plus
-        version: 2.20.0
-      - name: community.docker # Only required if you plan to use Molecule (see below)
-        version: 3.10.3
-    ```
-
-    **Note:** You can alternatively install the Ansible community distribution (what is known as the "old" Ansible) if you don't want to manage individual collections.
+If you want to use this role, you will need to use a supported version of Ansible core and Jinja2 as well as a few Ansible collections.
+
+For ease of use, you can install and/or upgrade Ansible core, Jinja2, and the aforementioned Ansible collections by running the following four commands on your Ansible host:
+
+```bash
+pip install --upgrade -r https://raw.githubusercontent.com/nginxinc/ansible-role-nginx/main/.github/workflows/requirements/requirements_ansible.txt
+curl -O https://raw.githubusercontent.com/nginxinc/ansible-role-nginx/main/.github/workflows/requirements/requirements_collections.yml
+ansible-galaxy install --force -r requirements_collections.yml
+rm -f requirements_collections.yml
+```
+
+This will also ensure you are deploying/running this role with a fully tested version of the aforementioned packages/collections.
+
+#### Ansible core
+
+- This role is developed and tested with [maintained](https://docs.ansible.com/ansible/devel/reference_appendices/release_and_maintenance.html) versions of Ansible core and Python.
+- When using Ansible core, you will also need to install the following Ansible collections:

+    - name: community.docker # Only required if you plan to use Molecule (see below)
+      version: 3.10.3
+  ```
+
 - You will need to run this role as a root user using Ansible's `become` parameter. Make sure you have set up the appropriate permissions on your target hosts.

-### Jinja2
+> [!TIP]
+> You can alternatively install the [Ansible community distribution](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html#selecting-an-ansible-package-and-version-to-install) (what is still known Ansible -- instead of Ansible core) if you don't want to manage individual collections.
+
+#### Jinja2
 
 - This role uses Jinja2 templates. Ansible core installs Jinja2 by default, but depending on your install and/or upgrade path, you might be running an outdated version of Jinja2. The minimum version of Jinja2 required for the role to properly function is `3.1`.
 - Instructions on how to install Jinja2 can be found in the [Jinja2 website](https://jinja.palletsprojects.com/en/3.1.x/intro/#installation).
 
-### Molecule (Optional)
+### Testing suite (Optional)
+
+If you want to contribute to this role, you will also need to install Ansible Lint and Molecule.
+
+#### Ansible Lint (Optional)
 
-- Molecule is used to test the various functionalities of the role. The recommended version of Molecule to test this role is `4.x`.
-- Instructions on how to install Molecule can be found in the [Molecule website](https://molecule.readthedocs.io/en/latest/installation.html). *You will also need to install the Molecule Docker driver.*
-- To run the NGINX Plus Molecule tests, you must copy your NGINX Plus license to the role's [`files/license`](https://github.com/nginxinc/ansible-role-nginx/blob/main/files/license/) directory.
+- Ansible Lint is used to lint the role for both Ansible best practices and potential Ansible/YAML issues.
+- Instructions on how to install Ansible Lint can be found in the [Ansible Lint website](https://ansible.readthedocs.io/projects/lint/installing/).
+- Once installed, using Ansible Lint is as easy as running:

+  ```bash
+  ansible-lint
+  ```
+
+- For ease of use, you can install and/or upgrade Ansible Lint by running the following command on your Ansible host:
