+# nginx-redirect-www
+
+## Overview
+The `nginx-redirect-www` role is designed to automate the process of setting up redirects from `www.domain.tld` to `domain.tld` for all domains and subdomains configured within the `{{nginx.directories.http.servers}}` directory. This role dynamically identifies configuration files following the pattern `*domain.tld.conf` and creates corresponding redirection rules.
+
+## Role Description
+This role performs several key tasks:
+1. **Find Configuration Files**: Locates all `.conf` files in the `{{nginx.directories.http.servers}}` directory that match the `*.*.conf` pattern, ensuring that only domain and subdomain configurations are selected.
+   
+2. **Filter Domain Names**: Processes each configuration file, extracting the domain names and removing both the `.conf` extension and the `{{nginx.directories.http.servers}}` path.
+
+3. **Prepare Redirect Domain Mappings**: Transforms the filtered domain names into a source-target mapping format, where `source` is `www.domain.tld` and `target` is `domain.tld`.
+
+4. **Include nginx-redirect-domain Role**: Applies the redirection configuration using the `nginx-redirect-domain` role with the dynamically generated domain mappings.
+
+## Notes
+- This role is designed to work in environments where domain and subdomain configurations follow the naming pattern `*domain.tld.conf`.
+- It automatically excludes any configurations that begin with `www.`, preventing duplicate redirects.
