WRF4GInstall

@@ -5 +5 @@
 Although in the following examples we will use the same computer to manage and run the experiments, scientists generally use a computer to prepare and manage the experiments (where WRF4G has to be installed) and different computing resources to run them (PBS or SGE Clusters, HPC infrastructures, stand-alone servers). We call '''User Interface (UI)''' to the computer where WRF4G is installed and '''Computing Resources (CR)''' to the nodes where a WRF experiment can run. In the following experiments the computer where the UI role is installed will act as CR.
 
-== Required Software ==
-
-WRF4G needs having the following software installed on both UI and CR:
-
- * '''x86_64 Linux'''
- * '''Python''', version >= 2.4 and < 3.0.
+== How to get WRF4G ==
+The latest official version can get it by direct download [http://www.meteo.macc.unican.es/work/WRF4G.tar.gz WRF4G.tar.gz]. Before you get it, you have to check the WRF4G requirements both UI and CR:
+* '''x86_64''' Linux
+{{{
+#!sh
+[user@localhost ~]$ uname -p
+x86_64

+* '''[http://www.python.org/ Python]''', version >= '''2.4''' and < '''3.0'''

-Download and unpack the distribution file  [http://www.meteo.macc.unican.es/work/WRF4G.tar.gz WRF4G.tar.gz] into the installation directory, for example your $HOME directory. 
+== Deploy WRF4G ==

+Download and unpack the distribution file into the deployment directory (e.g. `$HOME` directory).

-* Start the WRF4G Framework. This command will start the services needed by WRF4G to run.

+You can verify if WRF4G has been deployed properly by running the following command:
 {{{
