+and download the software, once it's downloaded install Docker Desktop with the default configuration.
+Note: to download Docker Desktop you need to create an account with Docker.

+```
+3. AWS access and secret key.
+
+### Deployment

+```bash
+$ docker-machine create --driver amazonec2 --amazonec2-access-key AKI******* --amazonec2-secret-key 8T93C*******  aws-sandbox
+```
+
+3. (Optional) To make sure you created the instance correctly and it's active, run:
+```bash
+$ docker-machine ls -t "30"
+```
+Should look something like this:
+```bash

+```
+
+4. Once the ec2 instance has been created on AWS run:
+```bash
+$ docker-compose -f docker-compose.prod.yml up -d --build
