+# Docker-GitLab Ansible Role README.md
+
+## Overview
+This Ansible role is designed for setting up and managing a GitLab server running in a Docker container. It automates the process of installing GitLab, configuring its environment, and managing dependencies such as a PostgreSQL database and an Nginx reverse proxy.
+
+## Features
+- **GitLab Installation**: Automatically deploys GitLab using Docker.
+- **External PostgreSQL Database**: Configures GitLab to use an external PostgreSQL database.
+- **Nginx Reverse Proxy Integration**: Includes tasks for setting up an Nginx reverse proxy for GitLab.
+- **Customizable Configuration**: Variables and templates allow for easy customization.
+
+## Requirements
+- Docker and Docker Compose installed on the target machine.
+- Ansible for automation.
+
+## Role Variables
+Variables are defined in `vars/main.yml`. Key variables include:
+- `docker_compose_instance_directory`: Directory for Docker Compose instances.
+- `database_instance`, `database_host`, `database_databasename`, `database_username`, `database_password`: Database configuration variables.
+- `database_version`: PostgreSQL version, with a default fallback.
+
+## Handlers
+- `recreate gitlab`: Restarts GitLab using Docker Compose when changes are detected.
+
+## Dependencies
+- `nginx-docker-reverse-proxy`: A role for setting up an Nginx reverse proxy for GitLab.
+
+## Template Files
+- `docker-compose.yml.j2`: Jinja2 template for the Docker Compose configuration.
+- Additional templates for database and proxy configuration.
+
+## Usage
+Include this role in your Ansible playbooks and specify the necessary variables. Run the playbook to deploy and configure GitLab in a Docker environment.
+
+For a detailed walkthrough and explanation of this role, refer to the conversation at [ChatGPT Session Transcript](https://chat.openai.com/share/1b0147bf-d4de-4790-b8ed-c332aa4e3ce3).
