+You can download LEMON from the LEMON web site:
+http://lemon.cs.elte.hu
+by following the download link. There you will find the issued distributions in form of \e .ta.gz files. If you want a developer version  (for example you want to contribute in developing the library LEMON) then you might want to use our Subversion repository. This case is not detailed here, so from now on we suppose that you downloaded a tar.gz file.
 
 
 \section installLEMON How to install LEMON
 
 In order to install LEMON you have to do the following
 
+Download the tarball and issue the following commands:
+
+\code
+tar xvzf lemon-0.3.1.tar.gz
+cd lemon-0.3.1
+./configure
+make
+make check (This is optional, but recomended. It runs a bunch of tests.)
+make install
+\endcode
+
+These commands install LEMON under /usr/local. If you want to install it to some other place, then pass the --prefix=DIR flag to ./configure.

-You will also want to assign data to the edges or nodes of the graph, for example a length or capacity function defined on the edges. You can do this in LEMON using so called \ref maps "maps". You can define a map on the nodes or on the edges of the graph and the value of the map (the range of the function) can be practically almost any type. Read more about maps \ref maps-page "here".

 - First we give two examples that show how to instantiate a graph. The
 first one shows the methods that add nodes and edges, but one will
 usually use the second way which reads a graph from a stream (file).
