 # WARP - a Webbased frontend for ARgparser in Python
 
+`warp` can be used to execute single Python file and Python modules. It captures
+calls to the `argparse` module of Python and renders a web GUI based on the
+options and arguments defined. It also displays the output of the program inside
+the web GUI and allows you to stop, pause and resume the Program, as well as
+downloading the output.
+
 ## Install
 
+Either get a stable version from PyPI, or install the current version from git
+
+    # Installation from PyPI
+    pip install warp
+
+    # Installation from git
     pip install git+https://git.k-fortytwo.de/christofsteel/warp/
 
 ## Usage

 ## Sample
 
+To test the capabilities of `warp` an example module was included. You can run
+it like this:
+
     warp -m warp.samples.hooked
+
+Since `warp` also makes use of the argparse module, `warp` itself can be //warped//.
+
+    warp -m warp.hook
+
+## How does it work?
+
+When `warp` is executed, it starts a flask webserver. The javascript of the 
+website reads the `/arguments` resource of the server, where the configuration
+of the argparser returned. In a seperate process the given program is executed
+using the `runpy` library, redirecting `sys.stdin` and `sys.stdout` to a 
+`multiprocessing.Queue`, which can be read by the warp process to display it
+via the web GUI.
+
+Additionally, `warp` adds an entry for `argparse` in the `sys.modules` list. Python
+looks first looks at this list, everytime a module is imported, to avoid 
+importing a module multiple times. This custom `argparse` module behaves similar
+to the original `argparse` module. In fact with the exception of the 
+`ArgumentParser.parse_args()` method, it works exactly like the original. 
+Once the program calls the `parse_args()` method, it blocks and waits for
+user interaction via the web GUI. Once the user submits the data, the process
+continues.
