+# Terraform Module: Install and Manage linuxpatch.com Agent and Service
+
+## Description
+
+This Terraform module automates the process of downloading, executing, and cleaning up an installation script from [linuxpatch.com](https://linuxpatch.com). Additionally, it ensures that the `linuxpatch-agent` service is running and enabled at startup.
+
+## Prerequisites
+
+- Terraform installed on the control node.
+- SSH access to the target host.
+- API key for [linuxpatch.com](https://linuxpatch.com).
+- SSH private key for authentication.
+
+## Variables
+
+- `api_key`: The API key required for the script execution. You should replace the placeholder with your actual API key.
+- `target_host`: The target host where the script will be executed.
+
+## Usage
+
+1. **Clone the repository or create the module files**:
+
+   Save the module content into a directory named `linuxpatch`.
+
+2. **Set up the variables**:
+
+   Open `variables.tf` and define the variables `api_key` and `target_host`.
+
+3. **Run Terraform Init**:
+
+   Initialize the Terraform module.
+
+   ```bash
+   terraform init
+   ```
