+
+[Syncthing](https://syncthing.net/) is a continuous file synchronization program. It synchronizes files between two or more computers 
+in real-time, safely protected from prying eyes.
+
+The Syncthing integration allows you to monitor states of your synced folders from within Home Assistant and set up automations based on the information.
+
+## Prerequisites
+
+To set up the monitoring you need to get an **API key**. Open the Syncthing web 
+interface(e.g., `http://127.0.0.1:8384`) in the browser and go to **Actions** -> **Settings**. You will find
+the key on the right of the settings dialog.
+
+{% include integrations/config_flow.md %}
+  
+## Integration Entities
+
+The Syncthing integration adds one sensor per syncing folder:
