Varnish Documentation

The official documentation contains a install guide, a tutorial and a reference.

• Documentation for the latest release 6.0
• Documentation for 5.2
• Documentation for 5.1

• Documentation for the deprecated release 4.0
• Documentation for old version 3.0 (unsupported)
• Documentation for older version 2.1 (unsupported)
• Documentation for the current development version (git master)
