 +
 +Unbound is a validating, recursive, caching DNS resolver. It is designed to be
 +fast and lean and incorporates modern features based on open standards. If you
 +have any feedback, we would love to hear from you. Don’t hesitate to
 +[create an issue on Github](https://github.com/NLnetLabs/unbound/issues/new)
 +or post a message on the [Unbound mailing list](https://lists.nlnetlabs.nl/mailman/listinfo/unbound-users).
 +You can learn more about Unbound by reading our
 +[documentation](https://unbound.docs.nlnetlabs.nl/).
 +
 +## Compiling
 +
 +Make sure you have the C toolchain, OpenSSL and its include files, and libexpat
 +installed. Unbound can be compiled and installed using:
 +
 +```
 +./configure && make && make install
 +```
 +
 +You can use libevent if you want. libevent is useful when using many (10000)
 +outgoing ports. By default max 256 ports are opened at the same time and the
 +builtin alternative is equally capable and a little faster.
 +
 +Use the `--with-libevent=dir` configure option to compile Unbound with libevent
 +support.
 +
 +## Unbound configuration
 +
 +All of Unbound's configuration options are described in the man pages, which
 +will be installed and are available on the Unbound
 +[documentation page](https://unbound.docs.nlnetlabs.nl/).
 +
 +An example configuration file is located in
 +[doc/example.conf](https://github.com/NLnetLabs/unbound/blob/master/doc/example.conf.in).
