 ## Deployment
 These deployment steps should be performed on the master node of the Docker Swarm:
+Use ssh command to connect to the master node using your AWS credentials (keypair.pem file):
+
+    ssh -i <your_keypair.pem> ubuntu@master-node-ip

 1. **Create Neighbors Configuration**:
     - Create a `neighbors.json` file ([view example](neighbors.json)) that specifies the neighbors for each node in your distributed algorithm network. 
 2. **Create Docker Config**:
-    - Use the `docker config create` command to create a Docker config from your `neighbors.json` file:
+    - In this step, you should create a configuration file that represents `neighbors.json`
+    - Use the `docker config create` command to create this configuration file:
     ```bash
-    docker config create <config_name> neighbors.json
+    docker config create <configuration file> neighbors.json
     ```
