-@node Usage
-@unnumbered Usage
-
-@itemize
-
-@item Build @command{tofuproxy}:
-
-@example
-$ git clone git://git.stargrave.org/tofuproxy.git
-$ cd tofuproxy
-$ go build
-@end example
-
-@item
-Generate CA-capable certificate for the proxy, that will issue ephemeral
-certificate to proxied domains:
-
-@example
-$ redo cert.pem
-@end example
-
-@item
-Create directory with output FIFOs and directory for stored certificate chains:
-
-@example
-$ ./mkfifos.sh
-$ mkdir certs
-@end example
-
-@item
-Run @command{tofuproxy} itself. By default it will bind to
-@code{[::1]:8080}, use @code{[::1]:53} DNS server for DANE requests
-(set to an empty string to disable DANE lookups):
-
-@example
-$ ./tofuproxy
-main.go:316: listening: [::1]:8080
-@end example
-
-@item Trust your newly generated CA:
-
-@example
-# cat /path/to/tofuproxy/cert.pem >> /etc/ssl/cert.pem
-@end example
-
-@item Point you HTTP/HTTPS clients to @code{http://localhost:8080}.
-
-@item Watch logs with @url{https://github.com/halturin/multitail, multitail}:
-
-@example
-$ ./multitail.sh
-@end example
-
-@end itemize
-
-When you encounter something requiring your attention and decision, you
-will be shown Tk-dialog through the @command{wish} invocation. GnuTLS'es
-@command{certtool} is used for certificate information printing.
