+ssh
+===
+
+Create ssh servers (and later, clients too) in node.js!
+
+Coming soon.
+
+installation
+============
+
+You'll need a version of [libssh](http://libssh.org/) with my patches:
+
+    git clone git://github.com/substack/libssh.git master
+    cd libssh
+    ./configure --prefix=$PREFIX && make && make install
+
+That should install libssh.pc, which is used by pkg-config during the
+wscript installation. Make sure libssh.pc got installed into your
+$PKG_CONFIG_PATH someplace.
+
+You can then install with [npm](http://npmjs.org):
+
+    npm install ssh
+
+Note: the above does not work yet, coming soon
