+For the user’s convenience, PEGASUS is distributed as a precompiled executive file. No special installation procedure is needed.
-After unpacking the distributive archive, the data files containing the necessary TMD parton densities in a proton (and conventional parton densities as well) are located inside the PEGASUS home directory (folder ''data'').
+However, please be sure that ''g++'', ''gfortran'' compilers and basic ''Qt4'' libraries are already
+installed in your system (to be precise, ''libc.so.6'', ''libgfortran.so.3'', ''libstdc++.so.6'', ''libQtGui.so.4'', ''libQtCore.so.4'', ''libQtSvg.so.4'' and ''libqwt.so.6'' are needed). After unpacking the distributive archive, all libraries and data files containing the necessary TMD parton densities in a proton (and conventional parton densities as well) are located inside the PEGASUS home directory (''lib'' and ''data'' folders).
 NOTE:
-**no calculation is allowed if there are some missing data files in the ''data'' folder.**

+Otherwise, the executive file can be just run from a terminal as
 <code>
 ./PEGASUS

-Otherwise, the path to ''libqwt.so.6'' library should be specified with
 <code>
 export LD_LIBRARY_PATH=/path/to/library
 </code>
+If a long-time calculation is needed, one can run console version as
+<code>
+./cPEGASUS filename.pegasus
+</code>
+with the user-defined setup saved to a configuration file ''filename.pegasus''.
