+# Mainnet Snapshots Recovery playbook
+
+This directory is simple example how to set up EN using this role. It comes with snapshots recovery enabled by default.\
+**Note that for simplicity it's using postgres database
+with a very unsecure password and the EN is just started on the same machine**
+
+To run this playbook, first install dependencies
+
+```shell
+ ansible-galaxy install -r requirements.yml
+ ``` 
+
+and then you can run the playbook using
+
+```shell
+ ansible-playbook playbook.yml -i hosts.ini -K
+ ``` 
+
+To see logs you can use
+
+```shell
+ docker logs en-external_node-1 
+ ```
