 Subversion (svn) is needed to obtain the source code. You need to be a registered Forge user and ask to join the DYNAMICO project.
-DYNAMICO requires the NetCDF library, including the F90 modules.
+DYNAMICO requires the NetCDF library, including the F90 modules. MPI is required for parallel execution but DYNAMICO can compile and run without MPI.
 
 == Getting DYNAMICO through svn ==
 
-svn co svn+ssh://mylogin@forge.ipsl.jussieu.fr/ipsl/forge/projets/dynamico/svn/codes/icosagcm/trunk
+svn co svn+ssh://mylogin@forge.ipsl.jussieu.fr/ipsl/forge/projets/dynamico/svn/codes/icosagcm/trunk DYNAMICO
 
-(mylogin should be your forge login)
+'mylogin' should be your forge login. svn will create the DYNAMICO directory and download the source code there.
 
 == Compiling DYNAMICO ==
 
+The compiling process is automated but some information is needed to guide it. This information is contained in text files in source:codes/icosagcm/trunk/arch . Sample files corresponding to a few machines (Ada at IDRIS, Curie at TGCC) are present. Assuming you compile on Ada :
+
+cd DYNAMICO
+./make_icosa -arch X64_ADA -parallel mpi -prod -jobs 8
+
+will compile DYNAMICO. The make_icosa script accepts keyword-value pairs which drive its behaviour. The most important option is arch=ARCH (here ARCH=X64_ADA). It directs make_icosa to use the information contained in :
+* arch/arch-ARCH.env
+* arch/arch-ARCH.fcm
+* arch/arch-ARCH.path
+
+The *.env file is a shell script that is executed by make_icosa. It sets up the environment for use by *.path. *.path defines paths to libraries and modules needed for compilation. *.fcm defines the commands used to compile, link, etc. as well as options to be passed to the compiler/linker .
