+@cindex pluggable transports, tor
+@deftp {Data Type} tor-transport-plugin
+Data type representing a Tor pluggable transport plugin in
+@code{tor-configuration}. Plugguble transports are programs
+that disguise Tor traffic, which can be useful in case Tor is
+censored. See the the Tor project's
+@url{https://tb-manual.torproject.org/circumvention/,
+documentation} and
+@url{https://spec.torproject.org/pt-spec/index.html,
+specification} for more information.
+
+Each transport plugin corresponds either to
+``ClientTransportPlugin ...'' or to
+``ServerTransportPlugin ...'' line in the default
+configuration file, see the @code{man tor}.
+Available @code{tor-transport-plugin} fields are:
+
+@table @asis
+@item @code{role} (default: @code{'client})
+This must be either @code{'client} or @code{'server}. Otherwise,
+an error is raised. Set the @code{'server} value if you want to
+run a bridge to help censored users connect to the Tor network, see
+@url{https://community.torproject.org/relay/setup/bridge/,
+the Tor project's brige guide}. Set the @code{'client} value
+if you want to connect to somebody else's bridge, see
+@url{https://bridges.torproject.org/, the Tor project's
+``Get Bridges'' page}. In both cases the required
+additional configuration should be provided via
+@code{#:config-file} option of @code{tor-configuration}.
+@item @code{protocol} (default: @code{"obfs4"})
+A string that specifies a pluggable transport protocol.
+@item @code{path-to-binary}
+This must be a ``file-like'' object or a string
+pointing to the pluggable transport plugin executable.
+This option allows the Tor daemon run inside the container
+to access the executable and all the references
+(e.g. package dependencies) attached to it.
