+# nginx-proxy-manager docker deployment
+
+## Introduction
+
+This is a docker-compose configuration to deploy an nginx-proxy-manager
+instance. It provides web site proxying via nginx, as well as SSL
+support via letsencrypt.
+
+## Custom Network
+
+To simplify inter-container communications when using a docker-compose
+file for each web site, create a custom network to be shared between
+nginx-proxy-manager and each web app.
+
+```
+$ docker network create npm-backend
+```
+
+To use this network, a networks section needs to be added to each
+docker-compose.yml file. In addition, the nginx-proxy-manager is set
+to use both it's default network, as well as the npm-backend network.
+For all of the web apps, the npm-backend will be set as the default network.
+
+```
+-----[ nginx-proxy-manager docker.compose.yml ]-----
+---
+version: '3'
+
+networks:
+  npm-backend:
+    external:
+      name: npm-backend
+
+services:
+  nginx-proxy-manager:
+(...)
+    networks:
+      - default
+      - npm-backend
+(...)
+
+-----[ each web app docker.compose.yml ]-----
+---
+version: '3.2'
+
+services:
+  web-app:
+(...)
+
+networks:
+  default:
+    external: true
+    name: npm-backend
+```
