+## Redis Service
+
+### Setup
+
+Copy the index file in this folder to the project root:
+
+```bash
+cd <project_folder>/
+
+cp -r nodock/_examples/redis/* .
+```
+
+### Usage
+
+```bash
+cd nodock/
+
+docker-compose up -d redis node nginx
+```
+
+By going to `127.0.0.1` in your browser you should be seeing a message indicating that `node` has successfully connected to `redis`.
