+FreeTubeSync is an Open API, Single User, synchronization REST server to allow for synchronization of data
+between machines.
+
+## What you can sync:
+* Watch History
+* Profiles / Subscriptions
+* Settings
+* Playlists
+* Search History
+
+# Setup
+
+To setup the API server, simple create a docker compose file with contents below, and run docker `compose up -d`
+
+```yaml
+services:
+  freetubesync:
+    image: forge.eumario.dev/eumario/freetubesync:latest
+    ports:
+      - "8080:8080"
+    volumes:
+      - ./data:/data
+```
+
+This project is currently only setup to be a Single User instance, no login/account system currently
+exists within the project setup.  If you want Multi-User support, it's best to create multiple docker
+containers for each user you want to have this capability for.
