 ### 1) Configure

 This command has two purposes :
 
  - Download and install all the requirements.
    Installing OCaml and the Core library may take some time (up to 20min on an old machine).
  - Create the file which contains all the dependencies for the binaries.  
-   It's not a Makefile, but a Ninja file (so don't type `make` is hopeless, type `ninja` instead)

+#### Compilation Flags (`<config_file>`)
 
 `<config_file>` is the path to the file which contains all the compilation flags (optimization flags, Lapack libary, etc). There are two example configure files in  ``$QP_ROOT/config`` : ``ifort.cfg`` and ``gfortran.cfg``.  You can copy these files to create a new file adapted to your architecture. 
 
-#### What utilization of the code will you do?
-
-* If you only want the binaries (for production workflow) use the flag
-  `--production`. It compiles faster. 
-* Else if you are a developer and you want to be able to compile specific modules use: `--development`. It will create the `build.ninja` in each module.

-Just type `ninja` if you are in `$QP_ROOT` (or `ninja -f $QP_ROOT/build.ninja` elsewhere). The compilation will take approximately 3 min.

-If you have set the `--developement` flag you can go in any module directory and run `ninja` to build only this particular module. You can type `ninja all` in a module to compile all the submodules.

 ### Error: ezfio_* is already defined.
 
 #### Why ?
 
-You have two or more ezfio configuration files for the same variable. Check files in `$QP_ROOT/install/EZFIO/config/`
