-# Compilation
----
+Installation
+------------
+RelaxSE is configured with [CMake](https://cmake.org) through the `configure` script
 
-## Dependencies
-- cmake (>3.5) python (>3.4)
-- fortran compiler (gfortran or ifort)
-- OpenMP and/or MPI for parallel compilation
-- blas and lapack libraries
+0. Dependencies
+    * cmake (>3.5) 
+    * python (>3.4)
+    * fortran compiler (gfortran or ifort)
+    * OpenMP and/or MPI for parallel compilation
+    * blas and lapack libraries
 
 NB: for linux it might be necessary to make a symlink for blas and lapack
 ln -s libblas.so.3 libblas.a
 ln -s liblapack.so.3 liblapack.a
 
-## Configure 
-- ./configure buildname
-- cd buildname
-- make
+1. Clone the repository:
+
+```
+git clone https://code.ill.fr/relaxse/relaxse-code
+```
+
+2. Run the `configure` script (options are printed by `configure --help`)
+
+```
+./configure buildname
+```
 
-## Running
-- INPUT, file.ref0, file.TraInt, file.TraOne in the same directory
-- relaxse.x 
+3. Compile with `make`
 
-## Compilation options
+```
+cd buildname
+make
+make test
+``` 
+
+**Compilation options**
 CC=`which gcc` CXX=`which g++` FC=`which gfortran` ./configure --build-type Debug builddir
 
+
+Running 
+-------
+1. Create a directory containing all input files:
+    INPUT, file.ref0, file.TraInt, file.TraOne 
+
+2. Lauch the code
+``` 
+./relaxse.x
+```
