+# Snapshots node
+
+## How it's works
+
+1. Setup the environment variables and setup the variables for the [minio-client](https://min.io) with your S3 credentials
+
+``` sh
+cp env.example env
+```
+
+2. Start the node
+
+By default, a snapshots will occur every 4 hours, and will upload it to S3
+
+``` sh
+docker compose up -d
+```
+
+## TO-DOs
+
+[ ] Prune the node before uploading the snapshots
