 The easiest way to get an Algo server running is to let it setup a _new_ virtual machine in the cloud for you.
 
 1. Setup an account on a cloud hosting provider. Algo supports [DigitalOcean](https://www.digitalocean.com/), [Amazon EC2](https://aws.amazon.com/), [Google Compute Engine](https://cloud.google.com/compute/), and [Microsoft Azure](https://azure.microsoft.com/).

 4. Start the deploy and follow the instructions by running: `./algo`. There are several optional features available. None are required for a fully functional VPN server. These features are described in greater detail in [ROLES.md](docs/ROLES.md).
 
 That's it! You now have an Algo VPN server on the internet.

-Certificates and configuration files that users will need are placed in the `configs` directory. Make sure to secure these files since many contain private keys. All files are prefixed with the IP address of the Algo VPN server.

 ## Setup an SSH Tunnel
 
-If you turned on the optional SSH tunneling role, then local user accounts will be created for each user in `config.cfg` and an SSH authorized_key files for them will be in the `configs` directory (user.ssh.pem). SSH user accounts do not have shell access, cannot authenticate with a password, and have limited tunneling options (e.g., `ssh -N` is required).

 Use the example command below to start an SSH tunnel by replacing `user` and `ip` with your own. Once the tunnel is setup, you can configure a browser or other application to use 127.0.0.1:1080 as a SOCKS proxy to route traffic through the Algo server.
