 Simple way to run a Monero daemon with some basic monitoring tools packaged in.
+
+## Setup
+
+The only requirements are [Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://docs.docker.com/compose/install/). Ensure those are installed on your system.
+
+```
+# Clone and enter the repository
+git clone https://github.com/lalanza808/docker-monero-node
+cd docker-monero-node
+
+# Setup Grafana password and blockchain storage location
+cp env-example .env
+vim .env
+
+# Start containers
+docker-compose up -d
+```
+
+Navigate to http://localhost:3000 and log into Grafana. Find the `Daemon Stats` dashboard to get those sweet, sweet graphs.
