 # Ansible Collection - mojaloop.iac
 
-Documentation for the collection.
+This document provides instructions for installing an Ansible collection from a Git repository and running a playbook to deploy the Mojaloop Control Center.
 
+## Step 1: Install the Ansible Collection
 
-ansible-galaxy collection install git+https://github.com/infitx-org/iac-ansible-collection-roles.git#/mojaloop/iac,main
-ansible-playbook mojaloop.iac.control_center_deploy -i /iac-run-dir/output/inventory
+To install the required Ansible collection from a Git repository, use the following command:
+
+```bash
+ansible-galaxy collection install git+https://github.com/mojaloop/iac-ansible-collection-roles.git#/mojaloop/iac,main
+```
+
+Explanation:
+
+- `ansible-galaxy collection install`: Command to install Ansible collections, in this example from a Git repository.
+- `git+https://github.com/mojaloop/iac-ansible-collection-roles.git`: Specifies the Git repository URL containing the Ansible collection.
+- `#/mojaloop/iac`: Defines the subdirectory path in the repository where the collection is located.
+- `main`: Indicates the branch of the Git repository to use for installation.
+
+## Step 2: Run the Ansible Playbook
+
+After installing the required Ansible collection, run the playbook to create resources using the following command:
+
+```bash
+ansible-playbook mojaloop.iac.control_center_deploy -i /iac-run-dir/output/inventory
+```
+
+Explanation:
+

+- `mojaloop.iac.control_center_deploy`: Specifies the playbook to deploy the Mojaloop Control Center. The playbook name is prefixed by the collection namespace (mojaloop.iac), which is required when the playbook is part of a collection.
