-# Feel++ as a library
+# Preriquisites
 
-Feel++ is installed as a library available thanks to the module. It is recommended to take that solution if you do not need to modify the library.
+* Read module documentation first.
+* The up to date documentation is available at [book.feelpp.org](https://book.feelpp.org/user-manual/) and should be the reference documentation.
 
-* After the module configuration in your shell config file, add:
+# Feel++ module (difficulty: easy)
+
+Feel++ is installed as a library available thanks to the module. (module av `module av 2>&1 | grep feelpp-` to list available
+versions.)
 
 ```sh
-module load latest.testing.profile
-module load science/feelpp/nightly
-export CC=/usr/bin/clang-3.7
-export CXX=/usr/bin/clang++-3.7
+module load feelpp/profile
+module load libs/feelpp-0.104
 ```
 
- * The first line is to load the meta module that contains every Feel++ dependancies.
- * The second is to load the library
- * The two lasts are to use the same compiler as the one the library was installed with.
+* The first line is to load the meta module that contains every Feel++ dependancies.
+* The second is to load the library (adapt release version)
 * Your root `CMakeLists.txt` has to be - considering you are trying to compile `yourCode.cpp`:
 
 ```sh

 feelpp_add_application(youApplication SRCS yourCode.cpp)
 ```
 
-* The last step is to run the `cmake /where/are/your/sources/files` and `make` commands in your build directory - typically `/ssd/YOUR_NAME/build`
+# Recompile Feel++ library (difficulty: average)
+
+Load feel++ dependency libraries
+
+```sh
+module load feelpp.profile
+```
+
+Place yourself in a directory. Then clone Feel++ sources from github, then place yourself in a build directory, execute cmake to generate the makefiles.
+
+```sh
+git clone git@github.com:feelpp/feelpp.git
+mkdir build && cd build
+../feelpp/configure -r
+```
+
+At this stage, you can compile the whole framework as usual (NB it takes a long time)
+
+```sh
+make
+make install # You should precise the --prefix option in configure to change default path.
+``` 
+
+A faster way is to compile only the desired application (it will only compile the required libraries only), for example
+```
+make -j8 feelpp_qs_laplacian 
+./quickstart/feelpp_qs_laplacian
+```
