  == How to get the code
- The code is currently (30/06/13) in beta, and is still expect to be modify before the official release (especially on the interface).
+ The code is currently (30/06/13) in beta.
  In order to download the code, you need to have bazaar install on your computer. Then you can download the code via the command
 {{{bzr branch lp:~maddevelopers/madgraph5/2.0.0beta4}}}  
 After that in order to update your version. You only need to do:
 {{{bzr pull}}}
-
  Those functionalities are going to be release in the 2.0.0beta version of the code.
  
- == How to use the code.
-
- You have a switch to run the reweight command from the launch/generate_events command.
- In addition you HAVE TO define/edit the reweight_card.dat, the syntax is explained in the file.
+ == How to use the code on the flight.
+
+ When running the generation of events (./bin/generate_events from the local directory or "launch" via the mg5 interface)
+ you will have two questions. The first one is:
+ {{{
+The following switches determine which programs are run:
+ 1 Run the pythia shower/hadronization:                   pythia=NOT INSTALLED
+ 2 Run PGS as detector simulator:                            pgs=NOT INSTALLED
+ 3 Run Delphes as detector simulator:                    delphes=NOT INSTALLED
+ 4 Decay particles with the MadSpin module:              madspin=OFF
+ 5 Add weight to events based on coupling parameters:   reweight=OFF
+  Either type the switch number (1 to 5) to change its default setting,
+  or set any switch explicitly (e.g. type 'madspin=ON' at the prompt)
+  Type '0', 'auto', 'done' or just press enter when you are done.
+ [0, 4, 5, auto, done, madspin=ON, madspin=OFF, madspin, reweight=ON, ... ][60s to answer] 
+>
+}}}
+ As you can see the reweight options is OFF by default, to set it on you can either type "5" (not adviced if you script) or "reweight=ON".
+ Then you should have:
+ {{{

+ }}}
+ Then the second question is (after that you just press enter on that question):
+   {{{
+Do you want to edit a card (press enter to bypass editing)?
+  1 / param     : param_card.dat
+  2 / run       : run_card.dat
+  3 / reweight  : reweight_card.dat
+ you can also
+   - enter the path to a valid card or banner.
+   - use the 'set' command to modify a parameter directly.
+     The set option works only for param_card and run_card.
+     Type 'help set' for more information on this command.
+ [0, done, 1, param, 2, run, 3, reweight, enter path][60s to answer] 
+   }}}
+ You '''HAVE TO define/edit''' the reweight_card.dat, the syntax is explained in the file.
+ The default file is basically empty and will make the re-weighting to crash since both theoretical hypothesis are identical.
+
+ == How to use the code afterwards.
 
  You can also use the madevent interface as explained below:
  
  1. go to the process directory. 
- 2. launch the '''./bin/madevent''' script
+ 2. launch the '''./bin/madevent''' script 
  3. type '''reweight RUN_NAME'''
  4. then you will see the following question:
