Installation of GnuCash can be simple, as most modern linux distributions come with GnuCash precompiled and ready to go. In fact, most likely, GnuCash is already installed. If you do not have GnuCash installed, the simplest method for installing it is to insert the installation CD that came with your distribution and follow the instructions.

The GnuCash home page contains detailed instructions on how to install GnuCash in the event your current distribution does not include it, or if you want to install a different version. You can also read the README file in the source code.
