49 The feisty meow scripts need initialization via the bootstrap process, which\n\
50 can be accomplished if one knows where the scripts are stored. For example,\n\
51 if feisty_meow is in the home directory, then this command will bootstrap the\n\
52 script configuration:\n\
54 bash $HOME/feisty_meow/scripts/core/reconfigure_feisty_meow.sh\n\
56 Or, if the feisty_meow folder is installed system-wide in a location such as\n\
57 /usr/local/feisty_meow, then this command would bootstrap the scripts:\n\
59 bash /usr/local/feisty_meow/scripts/core/reconfigure_feisty_meow.sh\n\
