Varnish Documentation

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

We’re trying to keep the official documentation in sync with the code. Both are kept in same source repository and both are available online:

• Documentation for the latest release 5.1
• Documentation for 5.0
• Documentation for the stable release 4.1
• 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)
