-### Server Audit Example
-Below is a screen shot of the server-auditing output when connecting to an unhardened OpenSSH v5.3 service:
+Basic server auditing:
+```
+ssh-audit localhost
+ssh-audit 127.0.0.1
+ssh-audit 127.0.0.1:222
+ssh-audit ::1
+ssh-audit [::1]:222
+```
+
+To run a standard audit against many servers (place targets into servers.txt, one on each line in the format of HOST[:PORT]):
+
+```
+ssh-audit -T servers.txt
+```
+
+To audit a client configuration (listens on port 2222 by default; connect using "ssh anything@localhost"):
+
+```
+ssh-audit -c
+```
+
+To audit a client configuration, with a listener on port 4567:
+```
+ssh-audit -c -p 4567
+```
+
+To  list all official built-in policies (hint: use resulting file paths with -P/--policy):
+```
+ssh-audit -L

+
+To run a policy audit against a server:
+```
+ssh-audit -P path/to/server_policy targetserver
+```
+
+To run a policy audit against a client:

+ssh-audit -c -P path/to/client_policy

+
+To run a policy audit against many servers:
+```
+ssh-audit -T servers.txt -P path/to/server_policy

+
+To create a policy based on a target server (which can be manually edited; see official built-in policies for syntax examples):
+```
+ssh-audit -M new_policy.txt targetserver

 ## ChangeLog
 ### v2.3.0 (???)
+ - Added new policy auditing functionality to test adherence to a hardening guide/standard configuration.  For an in-depth tutorial, see <link_goes_here>.
  - Created new man page (see `ssh-audit.1` file).
  - 1024-bit moduli upgraded from warnings to failures.
  - Many Python 2 code clean-ups, testing framework improvements, pylint & flake8 fixes, and mypy type comments; credit [Jürgen Gmach](https://github.com/jugmac00).
