+# Health CSP Crawler
+
+## Description
+
+This Ansible role automates the validation of [Content Security Policy (CSP)](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/CSP) enforcement for all configured domains by crawling them using a Puppeteer-based Node.js script.
+
+## Overview
+
+Designed for Archlinux systems, this role periodically checks whether web resources (JavaScript, fonts, images, etc.) are blocked by CSP headers. It integrates Python and Node.js tooling and installs a systemd service with timer support.
+
+## Features
+
+- **CSP Resource Validation:** Uses Puppeteer to simulate browser requests and detect blocked resources.
+- **Domain Extraction:** Parses all `.conf` files in the NGINX config folder to determine the list of domains to check.
+- **Automated Execution:** Registers a systemd service and timer for recurring health checks.
+- **Error Notification:** Integrates with `systemd-notifier` for alerting on failure.
+
+## Dependencies
+
+This role depends on the following:
+
+- [`nodejs`](../nodejs/)
+- [`npm`](../npm/)
+- [`systemd-notifier`](../systemd-notifier/)
+- [`systemd-timer`](../systemd-timer/)
+
+## Configuration
+
+Set the following variables to customize behavior:
+
+```yaml
+health_csp_crawler_folder: "{{ path_administrator_scripts }}health-csp/"
+on_calendar_health_csp_crawler: "daily"
+````

+# Node.js
+
+## Description
+
+This Ansible role installs Node.js on the target system using the native package manager.
+
+## Overview
+
+Optimized for Archlinux and Debian-based systems, this role ensures the presence of Node.js for use in Node-based applications or scripts. It serves as a foundational role for projects that depend on Node.js runtimes or utilities like Puppeteer.
+
+## Features
+
+- **Node.js Installation:** Installs the latest Node.js version available via the system's package manager.
+- **Idempotent Execution:** Ensures Node.js is only installed when missing.
+
+## Usage
+
+Include this role before running any tasks or roles that depend on Node.js:
+
+```yaml
+- name: Ensure Node.js is available
+  roles:
+    - nodejs

+# npm
+
+## Description
+
+This Ansible role installs npm and optionally runs `npm ci` within a given project directory. It is intended to streamline dependency installation for Node.js applications.
+
+## Overview
+
+Designed for use in Node-based projects, this role installs npm and can execute a clean install (`npm ci`) to ensure consistent dependency trees.
+
+## Features
+
+- **npm Installation:** Ensures the `npm` package manager is installed.
+- **Optional Project Setup:** Runs `npm ci` in a specified folder to install exact versions from `package-lock.json`.
+- **Idempotent:** Skips `npm ci` if no folder is configured.
+
+## Configuration
+
+Set `npm_project_folder` to a directory containing `package.json` and `package-lock.json`:
+
+```yaml
+vars:
+  npm_project_folder: /opt/scripts/my-node-project/
+```
