-## PURPOSE
---------------------
+## Purpose
 Givaro main features are implementations of the basic arithmetic of
 many mathematical entities: Primes fields, Extensions Fields, Finite
 Fields, Finite Rings, Polynomials, Algebraic numbers, Arbitrary
 precision integers and rationals (C++ wrappers over gmp), fixed
 precision integers.
 It also provides data-structures and templated classes for the
-manipulation of basic algebraic objects, such as vectors, matrices, 
+manipulation of basic algebraic objects, such as vectors, matrices,
 univariate polynomials (and therefore recursive multivariate).
 It contains different program modules and is fully compatible with the
 [FFLAS-FFPACK](http://linbox-team.github.io/fflas-ffpack) and
 [LinBox](http://linalg.org) linear algebra libraries.
 
 
 ## Download and install
---------------------
 
-For lastest releases, please check out [this website](http://github.com/linbox-team/givaro); older releases can be found on [that website](https://casys.gricad-pages.univ-grenoble-alpes.fr/givaro).

+The installation process depends on your download method. If you downloaded an archive:
 
 ```
-> tar -zxvf givaro-*.tar.gz
+> tar xzvf givaro-*.tar.gz
 > cd givaro-*
-> ./configure --prefix=##GIVAROROOT#
-> make install
+> ./configure --prefix=##GIVAROROOT##
+> make
+$ make install
 ```
 
+If you cloned the git repository directly, replace `./configure` by `./autogen.sh`:
+```
+> git clone git@github.com:linbox-team/givaro.git
+> cd givaro
+> ./autogen.sh --prefix=##GIVAROROOT##
+> make
+$ make install
+```
+Running ./autogen.sh will create a configure file that can be used directly for later re-compilations.
+
 *Configuration can be adapted. Check `configure --help` to print the parameter choices.*
 
-*In particular if GMP is not installed to the default location you might need to add for instance `--with-gmp=##GMPROOT#/gmp-x-y-z` to the configure line.*
+*In particular if GMP is not installed to the default location you might need to add for instance `--with-gmp=##GMPROOT##/gmp-x-y-z` to the configure line.*
