+## Standalone Usage
+
+you can target the integration tests to any host were you have ssh access
+
+rake -T gives you a list of suites you can run (well ignore directories which are obviously not suites for now)
+
+```
+± rake -T
+rake serverspec:data_bags  # Run serverspec suite data_bags
+rake serverspec:default    # Run serverspec suite default
+```
+
+run it with:
+
+```
+bundle install
+
+# default user and ssh-key
+
+bundle exec rake serverspec:default target_host=<name-or-ip-of-target-server>
+
+# or with user, host, password
+
+ASK_LOGIN_PASSWORD=true bundle exec rake serverspec:default target_host=192.168.1.222 user=stack
+```
