 # Get started
 
+Quick steps will setup a locally hosted dev server which will only run the sample_log plugin and log a line to captiveportal.log.
+
 ## Dependencies
 
-* Requires Python3 for a Postgres data type
-* Depends on iptables and conntrack
-* PostgreSQL for keeping track of clients
+* redis as backend for rq
 * rq for executing plugins (making firewall rules)
 
-## Run dev server
+## Install
 
     python setup.py install
-    python portal.py
 
 ## Run RQ worker in foreground
 
     rq worker -u redis://127.0.0.1:6379/
 
+## Run dev server
+
+    python portal.py
+
+Now visit the URL shown in the output and you'll be able to submit the portal form, wait for the background job to finish and be redirected to the default website (google.com). 
+
+By default only sample_log plugin is executed which logs a line to captiveportal.log when rq finishes running.

+* Captiveportal portal web app
+* Associated tools must be setup here

+## Portal web app

+1. A clients redirected HTTP traffic puts them in the portal webpage.
+2. They send a POST form to the /approve url. This can be with user info, personal info, or simply an approve button for a EULA. 
+3. The portal executes its plugins in the order that their config section appears in plugins.cfg.
+4. Each plugin is passed the request object from Bottle which contains form values among other things.

 Plugins are executed when the user clicks through the captive portal form, whether they submit data or just approve an EULA these plugins are executed.
