+### This sets up a Raspberry Pi as an all in one PiHole DNS Server with Reverse Proxy capability.
+### It is intended for use internally on the LAN only - not to be exposed directly to the internet!
+
+## Installation and Configuration
+
+If you just want to get up and running in the quickest time possible, grab all the files in
+the [doc/example/](https://github.com/jeff89179/nginx-proxy-manager/tree/master/doc/rpi-example)
+folder and run:
+
+```bash
+docker-compose up -d
+```
+
+### Configuration File
+
+**The configuration file needs to be provided by you!**
+
+Don't worry, this is easy to do.
+
+The app requires a configuration file to let it know what database you're using.
+
+Here's an example configuration for `mysql` (or mariadb) that is compatible with the docker-compose example below:
+
+```json
+{
+  "database": {
+    "engine": "mysql",
+    "host": "db",
+    "name": "npm",
+    "user": "npm",
+    "password": "npm",
+    "port": 3306
+  }
+}
+```
+
+Once you've created your configuration file it's easy to mount it in the docker container.
+
+**Note:** After the first run of the application, the config file will be altered to include generated encryption keys unique to your installation. These keys
+affect the login and session management of the application. If these keys change for any reason, all users will be logged out.
+
+
+### Database
+
+This app doesn't come with a database, you have to provide one yourself. Currently only `mysql/mariadb` is supported for the minimum versions:
+
+- MySQL v5.7.8+
+- MariaDB v10.2.7+
+
+It's easy to use another docker container for your database also and link it as part of the docker stack, so that's what the following examples
+are going to use.
+
+You'll have to create the proper users for the DB and grant them access. Change localhost to the IP your container uses. 
+
+```
+CREATE USER 'npm'@'nginx-proxy-manager_app_1.nginx-proxy-manager_default' IDENTIFIED BY 'npm';
+GRANT ALL PRIVILEGES ON npm.* TO 'npm'@'nginx-proxy-manager_app_1.nginx-proxy-manager_default';
+CREATE USER 'npm'@'localhost' IDENTIFIED BY 'npm';
+GRANT ALL PRIVILEGES ON npm.* TO 'npm'@'localhost';
+```
+
+### Running the App
+
+Via `docker-compose`:
+
+```yml
+version: "3"
+services:
+  app:
+    image: jc21/nginx-proxy-manager:latest
+    restart: always
+    ports:
+      # Public HTTP Port:
+      - 80:80
+      # Public HTTPS Port:
+      - 443:443
+      # Admin Web Port:
+      - 81:81
+    volumes:
+      # Make sure this config.json file exists as per instructions above:
+      - ./config.json:/app/config/production.json
+      - ./data:/data
+      - ./letsencrypt:/etc/letsencrypt
+    depends_on:
+      - db
+  db:
+    image: yobasystems/alpine-mariadb:latest
+    restart: always
+    environment:
+      MYSQL_ROOT_PASSWORD: "npm"
+      MYSQL_DATABASE: "npm"
+      MYSQL_USER: "npm"
+      MYSQL_PASSWORD: "password"
+    volumes:
+      - ./data/mysql:/var/lib/mysql
+```
+
+Then:
+
+```bash
+docker-compose up -d
+```
+
+
+### Running on Raspberry PI / ARM devices
+
+There are docker images for all versions of the Rasberry Pi with the exception of the really old `armv6l` versions.
+
+The `latest` docker image is a manifest of all the different architecture docker builds supported, so this means
+you don't have to worry about doing anything special and you can follow the common instructions above.
+
+Check out the [dockerhub tags](https://cloud.docker.com/repository/registry-1.docker.io/jc21/nginx-proxy-manager/tags)
+for a list of supported architectures and if you want one that doesn't exist,
+[create a feature request](https://github.com/jc21/nginx-proxy-manager/issues/new?assignees=&labels=enhancement&template=feature_request.md&title=).
+
+Also, if you don't know how to already, follow [this guide to install docker and docker-compose](https://manre-universe.net/how-to-run-docker-and-docker-compose-on-raspbian/)
+on Raspbian.
+
+
+### Initial Run
+
+After the app is running for the first time, the following will happen:
+
+- The database will initialize with table structures
+- GPG keys will be generated and saved in the configuration file
+- A default admin user will be created
+
+This process can take a couple of minutes depending on your machine.
+
+
+### Default Administrator User
+
+```
+Email:    admin@example.com
+Password: changeme
+```
+
+Immediately after logging in with this default user you will be asked to modify your details and change your password.
+
+
+### Advanced Options
+
+#### X-FRAME-OPTIONS Header
+
+You can configure the [`X-FRAME-OPTIONS`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options) header
+value by specifying it as a Docker environment variable. The default if not specified is `deny`.
+
+```yml
+  ...
+  environment:
+    X_FRAME_OPTIONS: "sameorigin"
+  ...
+```
+
+```
+... -e "X_FRAME_OPTIONS=sameorigin" ...
+```
