-@code{go.cypherpunks.ru} uses @url{https://www.cacert.org/, CACert.org}
-certificate authority, that is not included by default in some operating
-system distributions and probably you have to install it in your system,
-because @command{go get} uses HTTPS connections. If you have issues
-using either @code{sum.golang.org} or @code{proxy.golang.org}, then you
-can disable their usage with @env{GOPRIVATE=go.cypherpunks.ru/gogost}
-environment variable.
+@code{go.cypherpunks.ru} uses @code{ca.cypherpunks.ru} X.509 CA
+authority, that may complicate installation:

+@itemize
+
+@item Go's default @code{proxy.golang.org} and @code{sum.golang.org}
+services won't be able to verify @code{go.cypherpunks.ru}'s TLS
+authenticity, because there are no common trust anchors. You can skip
+their usage by setting @env{$GOPRIVATE=go.cypherpunks.ru}.
