+# Overview
+
+This repository contains the configuration and setup instructions for hosting web applications in a DMZ environment.
+
+# Deployment Instructions
+
+Upon approval and merge of a pull request a manual deployment and reload of the configuration need to be done on the hosting server.
+
+
+```bash
+cd /opt/WebHosting_DMZ
+docker compose up -d .
+# Reload the Nginx configuration as sometimes backend changes might change the backend ip addresses and the dns caching of nginx need to be refreshed
+docker exec nginx nginx -s reload
+```
