If you extract the ZIP archive you need to set execution permission for extracted files:

chmod +x argit arcompile arconfig

This is no necessary for bzip2 format.

Put these three files (argit, arcompile, arconfig) in a directory where other binaries are kept:

/usr/local/bin/
or
/usr/bin/
or
/home/your_username/bin/

make sure the $PATH variable contains this dir.

Run arconfig first.
