 ## About
 
-Services like [DigitalOcean](https://www.digitalocean.com/)'s droplets make it super easy to create deployment targets for websites and other Node.js projects. However, there are still a lot of manual steps developers have to do in order to get the servers setup, configured and ready to be used for production.
+Services like [DigitalOcean](https://www.digitalocean.com/)'s droplets or [Linode](https://www.linode.com/)'s linodes make it super easy to create deployment targets for websites and other Node.js projects. However, there are still a lot of manual steps developers have to do in order to get the servers setup, configured and ready to be used for production.
 
 The goal of this tool is to make all those deployment steps a single command. You should focus on developing the features of your project, and let this tool handle the server setup and deployment automation.
