  Is Windows supported?
 
 :A:
- The library installs and works on Windows though not formally supported as unit tests are currently posix system only. Pip versions >= 8.0 are required for binary package installation of `gevent` on Windows, a dependency of `ParallelSSH`. Though `ParallelSSH` is pure python code and will run on any platform that has a working Python interpreter, its `gevent` dependency contains native code which either needs a binary package to be provided for the platform or to be built from source. Binary packages for `gevent` are provided for OSX, Linux and Windows platforms as of this time of writing.

 :Q:
  Are SSH agents used?
 
 :A:
- All available keys in a running SSH agent in addition to SSH keys in the user's home directory, `~/.ssh/id_dsa`, `~/.ssh/id_rsa` et al are automatically used by ParallelSSH. Use of SSH agent can be disabled by creating a client as `ParallelSSHClient(allow_agent=False)`. `See documentation <http://parallel-ssh.readthedocs.org/en/latest/>`_ for more information.

   Is there a way to programmatically provide an SSH key?

-  Yes, use the `pkey` parameter of the `ParallelSSHClient class <http://parallel-ssh.readthedocs.org/en/latest/#pssh.ParallelSSHClient>`_. For example:
+  Yes, use the `pkey` parameter of the `ParallelSSHClient class <http://parallel-ssh.readthedocs.org/en/latest/#pssh.ParallelSSHClient>`_. There is a `load_private_key` helper function in `pssh.utils` that can be used to load any key type. For example:
 
-  >>> import paramiko
-  >>> client_key = paramiko.RSAKey.from_private_key_file('user.key')
