SFTP connection info for Pantheon
If you're developing your site using Pantheon's free development hosting, the process of connecting to the server directly using SFTP is a little different. The most up-to-date documentation is available in Pantheon's own documentation.
A tip: don't forget to change the default port value in your SFTP client. By default, the SFTP client tries to connect on port 22, and Pantheon's servers expect a connection through port 2222.
