 .SH DESCRIPTION
+\fIsession\fP - Session instance as returned by 
+.BR libssh2_session_init(3)
+
 Open a channel and initialize the SFTP subsystem. Although the SFTP subsystem
 operates over the same type of channel as those exported by the Channel API,
 the protocol itself implements its own unique binary packet protocol which
 must be managed with the libssh2_sftp_*() family of functions. When an SFTP
 session is complete, it must be destroyed using the
-\fIlibssh2_sftp_shutdown(3)\fP function.
